Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation, Policy [Policy Text Block]	Basis of Consolidation. Carrols Restaurant Group is a holding company and conducts all of its operations through its wholly-owned subsidiary, Carrols Corporation (“Carrols”) and Carrols' wholly-owned subsidiary, Carrols LLC, a Delaware limited liability company, and Carrols LLC's wholly-owned subsidiary Republic Foods, Inc., a Maryland corporation ("Republic Foods"). The unaudited condensed consolidated financial statements presented herein include the accounts of Carrols Restaurant Group and its wholly-owned subsidiary Carrols. Unless the context otherwise requires, Carrols Restaurant Group, Carrols, Carrols LLC and Republic Foods, Inc. are collectively referred to as the “Company.” All intercompany transactions have been eliminated in consolidation.
Fiscal Period, Policy [Policy Text Block]	Fiscal Year. The Company uses a 52-53 week fiscal year ending on the Sunday closest to December 31. The three and six months ended July 2, 2017 and July 3, 2016 each contained thirteen and twenty-six weeks, respectively.
Basis of Presentation, Policy [Policy Text Block]	Basis of Presentation. The accompanying unaudited condensed consolidated financial statements for the six months ended July 2, 2017 and July 3, 2016 have been prepared without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission and do not include certain of the information and the footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all normal and recurring adjustments considered necessary for a fair presentation of such unaudited consolidated financial statements have been included. The results of operations for the three and six months ended July 2, 2017 and July 3, 2016 are not necessarily indicative of the results to be expected for the full year.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates. The preparation of the accompanying unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the unaudited consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant items subject to such estimates include: accrued occupancy costs, insurance liabilities, evaluation for impairment of long-lived assets and franchise rights, lease accounting matters, the valuation of acquired assets and liabilities and the valuation of deferred income tax assets. Actual results could differ from those estimates.
Segment Reporting, Policy [Policy Text Block]	Segment Information. Operating segments are components of an entity for which separate financial information is available and is regularly reviewed by the chief operating decision maker in order to allocate resources and assess performance. The Company's chief operating decision maker currently evaluates the Company's operations from a number of different operational perspectives; however resource allocation decisions are made at a total-Company basis. The Company derives all significant revenues from a single operating segment. Accordingly, the Company views the operating results of its Burger King restaurants as one reportable segment.
Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. In determining fair value, the accounting standards establish a three level hierarchy for inputs used in measuring fair value as follows: Level 1 inputs are quoted prices in active markets for identical assets or liabilities; Level 2 inputs are observable for the asset or liability, either directly or indirectly, including quoted prices in active markets for similar assets or liabilities; and Level 3 inputs are unobservable and reflect our own assumptions. Financial instruments include cash, trade and other receivables, accounts payable and long-term debt. The carrying amounts of cash, trade and other receivables and accounts payable approximate fair value because of the short-term nature of these financial instruments. The fair value of the Carrols Restaurant Group 8.0% Senior Secured Second Lien Notes due 2022 is based on a recent trading value, which is considered Level 2, and at July 2, 2017 was approximately $293.6 million. Fair value measurements of non-financial assets and non-financial liabilities are primarily used in the impairment analysis of long-lived assets, goodwill and intangible assets. Long-lived assets and definite-lived intangible assets are measured at fair value on a nonrecurring basis using Level 3 inputs.
