Impairment of Long-Lived Assets and Other Lease Charges [Abstract]
Asset Impairment Charges [Text Block]	Impairment of Long-Lived Assets and Other Lease Charges The Company reviews its long-lived assets, principally property and equipment, for impairment at the restaurant level. If an indicator of impairment exists for any of its assets, an estimate of the undiscounted future cash flows over the life of the primary asset for each restaurant is compared to that long-lived asset’s carrying value. If the carrying value is greater than the undiscounted cash flow, the Company then determines the fair value of the asset and if an asset is determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value. For closed restaurant locations, the Company reviews the future minimum lease payments and related ancillary costs from the date of the restaurant closure to the end of the remaining lease term and records a lease charge for the lease liabilities to be incurred, net of any estimated sublease recoveries. The Company determined the fair value of restaurant equipment, for those restaurants reviewed for impairment, based on current economic conditions and the Company’s history of using these assets in the operation of its business. These fair value asset measurements rely on significant unobservable inputs and are considered Level 3 in the fair value hierarchy. The Level 3 assets measured at fair value associated with impairment charges recorded during the six months ended June 30, 2013 totaled $0.5 million. During the three months ended June 30, 2013, the Company recorded other lease charges of $1.6 million associated with the closure of four of the Company's restaurants in the second quarter of 2013. The Company also recorded impairment charges of $0.6 million consisting of approximately $0.3 million of capital expenditures at previously impaired restaurants and $0.3 million related to initial impairment charges at four underperforming restaurants in the three months ended June 30, 2013.

Impairment of Long-Lived Assets and Other Lease Charges

The Company reviews its long-lived assets, principally property and equipment, for impairment at the restaurant level. If an indicator of impairment exists for any of its assets, an estimate of the undiscounted future cash flows over the life of the primary asset for each restaurant is compared to that long-lived asset’s carrying value. If the carrying value is greater than the undiscounted cash flow, the Company then determines the fair value of the asset and if an asset is determined to be impaired, the loss is measured by the excess of the carrying amount of the asset over its fair value. For closed restaurant locations, the Company reviews the future minimum lease payments and related ancillary costs from the date of the restaurant closure to the end of the remaining lease term and records a lease charge for the lease liabilities to be incurred, net of any estimated sublease recoveries.

The Company determined the fair value of restaurant equipment, for those restaurants reviewed for impairment, based on current economic conditions and the Company’s history of using these assets in the operation of its business. These fair value asset measurements rely on significant unobservable inputs and are considered Level 3 in the fair value hierarchy. The Level 3 assets measured at fair value associated with impairment charges recorded during the six months ended June 30, 2013 totaled $0.5 million.

During the three months ended June 30, 2013, the Company recorded other lease charges of $1.6 million associated with the closure of four of the Company's restaurants in the second quarter of 2013. The Company also recorded impairment charges of $0.6 million consisting of approximately $0.3 million of capital expenditures at previously impaired restaurants and $0.3 million related to initial impairment charges at four underperforming restaurants in the three months ended June 30, 2013.
