Principles Of Consolidation	Principles of Consolidation The accompanying financial statements include the accounts of the Company, its wholly owned subsidiaries and a number of Company Drive-Ins in which a subsidiary has a controlling ownership interest. All intercompany accounts and transactions have been eliminated.
New Accounting Pronoucements	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers,” which requires entities to recognize revenue in the way it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most of the existing revenue recognition requirements in U.S. GAAP when it becomes effective. This pronouncement is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and is to be applied retrospectively, with early application not permitted. The Company is currently evaluating the effect that this pronouncement will have on its financial statements and related disclosures.

Disclosure of accounting policy regarding (1) the principles it follows in consolidating or combining the separate financial statements, including the principles followed in determining the inclusion or exclusion of subsidiaries or other entities in the consolidated or combined financial statements and (2) its treatment of interests (for example, common stock, a partnership interest or other means of exerting influence) in other entities, for example consolidation or use of the equity or cost methods of accounting. The accounting policy may also address the accounting treatment for intercompany accounts and transactions, noncontrolling interest, and the income statement treatment in consolidation for issuances of stock by a subsidiary.
