Restructuring Costs and Asset Impairment Charges [Abstract]
Impairment or Disposal of Long-Lived Assets [Policy Text Block]	Impairment of Long-Lived Assets. The Company assesses the potential impairment of long-lived assets, principally property and equipment, by determining whether the carrying value of these assets can be recovered over their respective remaining useful lives through undiscounted future operating cash flows. Impairment is reviewed whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Impairment indicators at the restaurant level include low operating cash flows, declining sales and if the ratio of trailing twelve months cash flows extended over the remaining lease term does not exceed the net book value of the asset group. Impairment indicators on a consolidated basis includes consideration of any impact from a decline in the Company's market value. 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 any ROU asset impairment or lease-related costs during the remaining term, net of any estimated sublease recoveries.
