I was in the Kansas City area last week and the Chipotle I visited had a line until 7:30PM that night. At 7:30PM my receipt said 850 meals had been served that day. My meal costs $10. I saw a family there order 3 meals, not counting the McDonald's they brought in for one of their kids. The store manager didn't seem to mind. Lots of couples ordered meals. I would guess the average ticket was around $10. Do the math. Chiptole is a gold mine.
One more thing. Employee moral seemed very high and the place was very clean. I could have been in any city in the USA. Their product is very uniform.
