Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition The Company recognizes revenue, net of discounts and incentives, when payment is tendered at the point of sale. The Company recognizes a liability for offers of free food by estimating the cost to satisfy the offer based on company–specific historical redemption patterns for similar promotions. These costs are recognized in other operating costs in the consolidated statement of operations and in accrued liabilities in the consolidated balance sheet. The Company reports revenue net of sales taxes and other sales related taxes collected from customers and remitted to governmental taxing authorities.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” as amended by multiple standards updates. The pronouncement was issued to clarify the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements for U.S. GAAP and IFRS. The pronouncement is effective for reporting periods beginning after December 15, 2017. The expected adoption method of ASU 2014-09 is being evaluated by the Company, and the adoption is not expected to have a significant impact on the Company’s consolidated financial position or results of operations. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842).” The pronouncement requires the recognition of a liability for lease obligations and a corresponding right-of-use asset on the balance sheet and disclosure of key information about leasing arrangements. This pronouncement is effective for reporting periods beginning after December 15, 2018 using a modified retrospective adoption method. The Company is currently evaluating the provisions of ASU No. 2016-02 to determine how it will be affected and expects that the primary impact of adopting the new standard will be to record assets and obligations for current operating leases. In March 2016, the FASB issued ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718).” The pronouncement was issued to simplify the accounting for share-based payment transactions, including income tax consequences, the classification of awards as either equity or liabilities, and the classification on the statement of cash flows. This pronouncement is effective for reporting periods beginning after December 15, 2016. The expected adoption method of ASU 2016-09 is being evaluated by the Company, and the impact of the adoption has not yet been determined. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326).” The pronouncement was issued to provide more decision-useful information about the expected credit losses on financial instruments and changes the loss impairment methodology. This pronouncement is effective for reporting periods beginning after December 15, 2019 using a modified retrospective adoption method. A prospective transition approach is required for debt securities for which an other-than-temporary impairment had been recognized before the effective date. The impact of the adoption of ASU 2016-13 is not expected to have a significant impact on the Company’s consolidated financial position or results of operations.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In June 2014, the FASB issued ASU No. 2014-12, “Compensation – Stock Compensation (Topic 718).” The pronouncement was issued to clarify the accounting for share-based payments when the terms of an award provide that a performance target could be achieved after the requisite service period. The pronouncement was effective for reporting periods beginning after December 15, 2015, and the Company adopted the guidance prospectively. The adoption of ASU 2014-12 did not have a significant impact on the Company’s consolidated financial position or results of operations. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40).” The pronouncement was issued to provide guidance concerning accounting for fees in a cloud computing arrangement. The pronouncement was effective for reporting periods beginning after December 15, 2015, and the Company adopted the guidance prospectively. The adoption of ASU 2015-05 did not have a significant impact on the Company’s consolidated financial position or results of operations.

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
