Fair Value Disclosures [Abstract]
Impairments	Impairments We measure certain assets and liabilities at fair value on a nonrecurring basis, including long-lived assets that have been reduced to fair value when they are held for sale and long-lived assets that are written down to fair value when they are impaired. We evaluate the carrying amount of long-lived assets held and used in the business periodically and when facts and circumstances indicate that an impairment may exist. A long-lived asset group is considered impaired when the carrying value of the asset group exceeds its fair value. The impairment loss recognized is the excess of carrying value above its fair value. The estimation of fair value requires significant judgment regarding future restaurant performance and market-based real estate appraisals. To estimate fair value for locations where we own the land and building, we obtain appraisals from third-party real estate valuation firms based on sales of comparable properties in the same area as our restaurant location, which we believe approximates fair value. We use discounted future cash flows to estimate fair value of long-lived assets for our leased locations. Our weighted average cost of capital is used as the discount rate in our fair value measurements for leased locations, which is considered a Level 3 measurement. A reasonable change in this discount rate would not have a significant impact on these fair value measurements. No impairment charges were recorded in either the three months ended July 29, 2016, or July 24, 2015, respectively.

We measure certain assets and liabilities at fair value on a nonrecurring basis, including long-lived assets that have been reduced to fair value when they are held for sale and long-lived assets that are written down to fair value when they are impaired.

We evaluate the carrying amount of long-lived assets held and used in the business periodically and when facts and circumstances indicate that an impairment may exist. A long-lived asset group is considered impaired when the carrying value of the asset group exceeds its fair value. The impairment loss recognized is the excess of carrying value above its fair value. The estimation of fair value requires significant judgment regarding future restaurant performance and market-based real estate appraisals. To estimate fair value for locations where we own the land and building, we obtain appraisals from third-party real estate valuation firms based on sales of comparable properties in the same area as our restaurant location, which we believe approximates fair value. We use discounted future cash flows to estimate fair value of long-lived assets for our leased locations. Our weighted average cost of capital is used as the discount rate in our fair value measurements for leased locations, which is considered a Level 3 measurement. A reasonable change in this discount rate would not have a significant impact on these fair value measurements.

No impairment charges were recorded in either the three months ended July 29, 2016, or July 24, 2015, respectively.
