Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments consisting of normal recurring adjustments necessary for a fair presentation of its financial position and results of operations and cash flows for the periods presented. Interim results of operations are not necessarily indicative of the results that may be achieved for the full year. The financial statements and related notes do not include all information and footnotes required by GAAP for annual reports. This quarterly report should be read in conjunction with the consolidated financial statements included in the Company’s annual report on Form 10-K for the year ended December 30, 2015. The Company uses a 52- or 53-week fiscal year ending on the last Wednesday of the calendar year. In a 52-week fiscal year, each quarter includes 13 weeks of operations; in a 53-week fiscal year, the first, second and third quarters each include 13 weeks of operations and the fourth quarter includes 14 weeks of operations. Every six or seven years a 53-week fiscal year occurs. Fiscal 2015 and 2016 are both 52-week years, ending on December 30, 2015, and December 28, 2016, respectively. Revenues, expenses, and other financial and operational figures may be elevated in a 53-week year. Holdings has no material assets or operations. Holdings and Holdings’ direct subsidiary, EPL Intermediate, Inc. (“Intermediate”), guarantee EPL’s 2014 Revolver (see Note 4) on a full and unconditional basis and Intermediate has no subsidiaries other than EPL. EPL is a separate and distinct legal entity, and has no obligation to make funds available to Intermediate. EPL and Intermediate may pay dividends to Intermediate and to Holdings, respectively. Under the 2014 Revolver, Holdings may not make certain payments such as cash dividends, except that it may, inter alia, (i) pay up to $1 million per year to repurchase or redeem qualified equity interests of Holdings held by past or present officers, directors, or employees (or their estates) of the Company upon death, disability, or termination of employment, (ii) pay under its income tax receivable agreement (the “TRA”), and, (iii) so long as no default or event of default has occurred and is continuing, (a) make non-cash repurchases of equity interests in connection with the exercise of stock options by directors and officers, provided that those equity interests represent a portion of the consideration of the exercise price of those stock options, (b) pay up to $2.5 million per year pursuant to stock option plans, employment agreements, or incentive plans, (c) make up to $5 million in other restricted payments per year, and (d) make other restricted payments, provided that such payments would not cause, in each case, on a pro forma basis, (x) its lease-adjusted consolidated leverage ratio to equal or exceed 4.25 times and (y) its consolidated fixed charge coverage ratio to be less than 1.75 times.
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Holdings and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and revenue and expenses during the period reported. Actual results could materially differ from those estimates. The Company’s significant estimates include estimates for impairment of goodwill, intangible assets and property and equipment, insurance reserves, lease termination liabilities, closed store reserves, stock-based compensation, income tax receivable agreement liability, and income tax valuation allowances.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly-liquid instruments with a maturity of three months or less at the date of purchase to be cash equivalents.
Restricted Cash	Restricted Cash The Company’s restricted cash represents cash collateral to one commercial bank for Company credit cards.
Reclassifications	Reclassifications Certain comparative prior year amounts in the condensed consolidated financial statements and accompanying notes have been reclassified to conform to the current year presentation. These reclassifications have no effect on previously-reported working capital, net income, earnings per share, stockholders’ equity, or cash flows.
Liquidity	Liquidity The Company’s principal liquidity requirements are to service our debt and to meet capital expenditure needs. At March 30, 2016, the Company’s total debt (including capital lease liabilities) was $121.1 million. The Company’s ability to make payments on its indebtedness and to fund planned capital expenditures depends on available cash and on its ability to generate adequate cash flows in the future, which, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory, and other factors that are beyond the Company’s control. Based on current operations, the Company believes that its cash flow from operations, available cash of $8.9 million at March 30, 2016, and available borrowings under the 2014 Revolver (which availability was approximately $72.3 million at March 30, 2016) will be adequate to meet the Company’s liquidity needs for the next 12 months.
Gain on recovery of insurance proceeds	Gain on recovery of insurance proceeds In November 2015, one of the Company’s restaurants incurred damage resulting from a fire. During the thirteen weeks ended March 30, 2016, we incurred costs directly related to the fire of $48,000 and recognized a gain of $289,000 resulting from the receipt from the insurance company of $400,000 in cash.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods therein (our fiscal year 2018). Early application is permitted. We are currently evaluating the impact of this guidance on our Condensed Consolidated Financial Statements. In February 2016, the FASB issued ASU 2016-02, “Leases.” The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact of the pending adoption of the new standard on the consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, "Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities." The pronouncement requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income, requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset, and eliminates the requirement for public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost. These changes become effective for the Company's fiscal year beginning December 28, 2017 and interim periods within that fiscal year. The impact of this expected adoption of ASU 2016-01 is being evaluated by the Company. In November 2015, the FASB issued ASU No. 2015-17, “Income Taxes” which requires that deferred tax liabilities and assets be classified as noncurrent in a classified balance sheet. Prior to the issuance of the standard, deferred tax liabilities and assets were required to be separately classified into a current amount and a noncurrent amount in the balance sheet. The new accounting guidance represents a change in accounting principle and the standard is required to be adopted in annual periods beginning after December 15, 2016. After the adoption of this ASU all deferred tax assets and liabilities will be classified as noncurrent on the consolidated balance sheet. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330).” The pronouncement was issued to simplify the measurement of inventory and changes the measurement from lower of cost or market to lower of cost and net realizable value. This pronouncement is effective for reporting periods beginning after December 15, 2016. The adoption of ASU 2015-11 is not expected to have a significant impact on the Company’s consolidated financial position or results of operations. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (ASU 2014-09)”, which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The revised revenue standard is effective for public entities for annual periods beginning after December 15, 2017, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the impact of the Company’s pending adoption of ASU 2014-09 on the Company’s financial statements and has not yet determined the method by which it will adopt the standard in fiscal 2018. In August 2014, the FASB issued ASU No. 2014-15, Going Concern (“ASU 2014-15”). ASU 2014-15 provides GAAP guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company’s ability to continue as a going concern within one year from the date the financial statements are issued. The standard will be effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016. Early application is permitted for annual or interim reporting periods for which the financial statements have not previously been issued. Upon adoption the Company will use the guidance in ASU 2014-15 to assess going concern.
Subsequent Events	Subsequent Events Subsequent to March 30, 2016, the Company and a franchisee each opened one new restaurant. On May 4, 2016, the Company received $600,000 of insurance proceeds related to a restaurant damaged by fire in 2015. The Company evaluated subsequent events that have occurred after March 30, 2016, and determined that there were no other events or transactions occurring during this reporting period that require recognition or disclosure in the condensed consolidated financial statements.
Concentration of Risk	Concentration of Risk Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally-insured limits. The Company has never experienced any losses related to these balances. The Company had one supplier for which amounts due at March 30, 2016 totaled 15% of the Company’s accounts payable. As of December 30, 2015, the Company had two different suppliers for which amounts totaled 12% and 11% of the Company’s accounts payable. Purchases from the Company’s largest supplier totaled 33% for the thirteen weeks ended March 30, 2016, and 36% for the thirteen weeks ended April 1, 2015, of the Company’s purchases. Company-operated and franchised restaurants in the greater Los Angeles area generated, in the aggregate, approximately 76% and 78% of total revenue for the thirteen weeks ended March 30, 2016 and April 1, 2015.
Goodwill and Indefinite Lived Intangible Assets	Goodwill and Indefinite Lived Intangible Assets The Company’s indefinite lived intangible assets consist of trademarks. Goodwill represents the excess of cost over fair value of net identified assets acquired in business combinations accounted for under the purchase method. The Company does not amortize its goodwill and indefinite lived intangible assets. Goodwill resulted from historical acquisitions. Upon the sale of a restaurant, we decrement goodwill. The amount of goodwill included in the cost basis of the asset sold is determined based on the relative fair value of the portion of the reporting unit disposed of compared to the fair value of the reporting unit retained. The Company performs annual impairment tests for goodwill during the fourth fiscal quarter of each year, or more frequently if impairment indicators arise. The Company reviews goodwill for impairment utilizing either a qualitative assessment or a two-step process. If the Company decides that it is appropriate to perform a qualitative assessment and concludes that the fair value of a reporting unit more likely than not exceeds its carrying value, no further evaluation is necessary. If the Company performs the two-step process, the first step of the goodwill impairment test is used to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step is performed to measure the amount of impairment by comparing the carrying amount of the goodwill to a determination of the implied value of the goodwill. If the carrying amount of goodwill is greater than the implied value, an impairment charge is recognized for the difference. The Company performs annual impairment tests for indefinite lived intangible assets during the fourth fiscal quarter of each year, or more frequently if impairment indicators arise. An impairment test consists of either a qualitative assessment or a comparison of the fair value of an intangible asset with its carrying amount. The excess of the carrying amount of an intangible asset over its fair value is its impairment loss. The assumptions used in the estimate of fair value are generally consistent with the past performance of the Company’s reporting segment and are also consistent with the projections and assumptions that are used in current operating plans. These assumptions are subject to change as a result of changing economic and competitive conditions. The Company did not identify any indicators of potential impairment during the thirteen weeks ended March 30, 2016, and therefore did not perform any impairment review, nor did the Company record any impairment.
Income Taxes	Income Taxes The provision for income taxes, income taxes payable and deferred income taxes is determined using the asset and liability method. Deferred tax assets and liabilities are determined based on temporary differences between the financial carrying amounts and the tax bases of assets and liabilities using enacted tax rates in effect in the years in which the temporary differences are expected to reverse. On a periodic basis, the Company assesses the probability that its net deferred tax assets, if any, will be recovered. If, after evaluating all of the positive and negative evidence, a conclusion is made that it is more likely than not that some portion or all of the net deferred tax assets will not be recovered, a valuation allowance is provided by charging to tax expense to reserve the portion of deferred tax assets which are not expect to be realized. The Company reviews its filing positions for all open tax years in all U.S. federal and state jurisdictions where the Company is required to file. When there are uncertainties related to potential income tax benefits, in order to qualify for recognition, the position the Company takes has to have at least a “more likely than not” chance of being sustained (based on the position’s technical merits) upon challenge by the respective authorities. The term “more likely than not” means a likelihood of more than 50 percent. Otherwise, the Company may not recognize any of the potential tax benefit associated with the position. The Company recognizes a benefit for a tax position that meets the “more likely than not” criterion at the largest amount of tax benefit that is greater than 50 percent likely of being realized upon its effective resolution. Unrecognized tax benefits involve management’s judgment regarding the likelihood of the benefit being sustained. The final resolution of uncertain tax positions could result in adjustments to recorded amounts and may affect our results of operations, financial position, and cash flows. The Company’s policy is to recognize interest and penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties at March 30, 2016, or at December 30, 2015, and did not recognize interest or penalties during the thirteen weeks ended March 30, 2016, or April 1, 2015, since there were no material unrecognized tax benefits. Management believes no material changes to the amount of unrecognized tax benefits will occur within the next twelve months. On July 30, 2014, the Company entered into the TRA. The TRA calls for the Company to pay to its pre-IPO stockholders 85% of the savings in cash that the Company realizes in its taxes as a result of utilizing its net operating losses and other tax attributes attributable to preceding periods.
