Impairment of Long-Lived Assets [Abstract]
Impairment of Long-Lived Assets	4. Impairment of Long-Lived Assets During the three and nine months ended September 30, 2017, we recognized non-cash impairment charges of $2,427 and $4,441  ($1,475 and $2,699 net of tax, respectively), representing substantially all of the value of the long-lived assets of a small number of underperforming Chipotle restaurants, in loss on disposal and impairment of assets on the condensed consolidated statement of income ($0.05 and $0.09 per basic and diluted earnings per share). The fair value of the impaired restaurants was determined using Level 3 inputs (unobservable inputs) based on a discounted cash flow method.
