Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	PRINCIPLES OF CONSOLIDATION — The consolidated condensed interim financial statements include the accounts of Ark Restaurants Corp. and all of its wholly-owned subsidiaries, partnerships and other entities in which it has a controlling interest, collectively herein referred to as the “Company”. Also included in the consolidated condensed interim financial statements are certain variable interest entities (“VIEs”). All significant intercompany balances and transactions have been eliminated in consolidation.
Reclassification, Policy [Policy Text Block]	RECLASSIFICATIONS — Certain reclassifications of prior period balances related to the income statement presentation of $822,000 of certain administrative fees related to catering revenue received have been reclassified from payroll expense to revenue to conform to the current period presentation.
Seasonality [Policy Text Block]	SEASONALITY — The Company has substantial fixed costs that do not decline proportionally with sales. The first and second fiscal quarters, which include the winter months, usually reflect lower customer traffic than in the third and fourth fiscal quarters. In addition, sales in the third and fourth fiscal quarters can be adversely affected by inclement weather due to the significant amount of outdoor seating at the Company’s restaurants.
Fair Value of Financial Instruments, Policy [Policy Text Block]	FAIR VALUE OF FINANCIAL INSTRUMENTS — The carrying amount of cash and cash equivalents, receivables, accounts payable and accrued expenses approximate fair value due to the immediate or short-term maturity of these financial instruments. The fair values of notes receivable and payable are determined using current applicable rates for similar instruments as of the consolidated condensed balance sheet date and approximate the carrying value of such debt instruments.
Cash and Cash Equivalents, Policy [Policy Text Block]	CASH AND CASH EQUIVALENTS — Cash and cash equivalents include cash on hand, deposits with banks and highly liquid investments generally with original maturities of three months or less. Outstanding checks in excess of account balances, typically vendor payments, payroll and other contractual obligations disbursed after the last day of a reporting period are reported as a current liability in the accompanying consolidated condensed balance sheets.
Supplier Concentration [Policy Text Block]	CONCENTRATIONS OF CREDIT RISK — Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The Company reduces credit risk by placing its cash and cash equivalents with major financial institutions with high credit ratings. At times, such amounts may exceed Federally insured limits. Accounts receivable are primarily comprised of normal business receivables, such as credit card receivables, that are paid off in a short period of time and amounts due from the hotel operators where the Company has a location, and are recorded when the products or services have been delivered. The Company reviews the collectability of its receivables on an ongoing basis, and provides for an allowance when it considers the entity unable to meet its obligation. The concentration of credit risk with respect to accounts receivable is generally limited due to the short payment terms extended by the Company and the number of customers comprising the Company’s customer base. For the 13-week periods ended December 31, 2016 and January 2, 2016, the Company did not make purchases from any one vendor that accounted for 10% or greater of total purchases for the respective period.
Segment Reporting, Policy [Policy Text Block]	SEGMENT REPORTING — As of December 31, 2016, the Company owned and operated 22 restaurants and bars, 19 fast food concepts and catering operations, exclusively in the United States, that have similar economic characteristics, nature of products and service, class of customers and distribution methods. The Company believes it meets the criteria for aggregating its operating segments into a single reporting segment in accordance with applicable accounting guidance.
Recently Adopted Accounting Standards [Policy Text Block]	RECENTLY ADOPTED ACCOUNTING STANDARDS — In June 2014, the FASB issued guidance which clarifies the recognition of stock-based compensation over the required service period, if it is probable that the performance condition will be achieved. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015 and should be applied prospectively. The adoption of this guidance did not have any impact on the Consolidated Condensed Financial Statements. In January 2015, the FASB issued guidance simplifying the income statement presentation by eliminating the concept of extraordinary items. Extraordinary items are events and transactions that are distinguished by their unusual nature and by the infrequency of their occurrence. Eliminating the extraordinary classification simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. The amendments are effective for annual reporting periods, including interim periods within those reporting periods, beginning after December 15, 2015. The adoption of this guidance did not have any impact on the Consolidated Condensed Financial Statements. In February 2015, the FASB amended the consolidation standards for reporting entities that are required to evaluate whether they should consolidate certain legal entities. Under the new guidance, all legal entities are subject to reevaluation under the revised consolidation model. Specifically, the guidance (i) modifies the evaluation of whether limited partnerships and similar legal entities are variable interest entities (VIEs) or voting interest entities; (ii) eliminates the presumption that a general partner should consolidate a limited partnership; (iii) affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (iv) provides a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act for registered money market funds. The amendments are effective for annual reporting periods, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. The adoption of this guidance did not have any impact on the Consolidated Condensed Financial Statements.
New Accounting Pronouncements, Policy [Policy Text Block]	NEW ACCOUNTING STANDARDS NOT YET ADOPTED — In January 2017, the FASB issued guidance clarifying the definition of a business. The update provides that when substantially all the fair value of the assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. The new rules will be effective for the Company in the first quarter of 2019. The Company is currently evaluating the potential impact adoption of this guidance on its Consolidated Condensed Financial Statements. In January 2017, the FASB guidance simplifying the test for goodwill impairment. The update simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount. The new rules will be effective for the Company in the first quarter of 2021. The Company is currently evaluating the potential impact adoption of this guidance on its Consolidated Condensed Financial Statements.
