This is one of the great things about living in the Denver area.
I knew of Chipotle when it was seriously just a local restaurant around here, because here is where it started. When they opened one up right near my house, I was in love.
No, I really don't like Mexican food, but Chipotle burritos pretty much top my list for fast food. The quality is insanely good; all the products (meat & veggies) are naturally grown, no hormones or any of that good stuff.
The size of the burritos is massive, especially depending on what you put in them. I think I only finish mine because I'm so picky I only get rice, fajita vegetables, black beans and meat. :P
The menu is simple, but there are a -lot- of hidden items. You can get hard AND soft shell tacos, you can get quesadillas, you can get salads made out of any of the meats... It's actually pretty neat. Their chips are freakin' top notch, too.
I've been eating Chipotle for like.. 5 years or more now, I guess. :P I love it. You'll never get anything but a good review from me.
Chicken quesadillas, carnitas fajita burritos with black beans, and chicken burritos are the three things I recommend. (Carnitas are the shredded pork, very .. not spicy. Barbacoa is the shredded beef, it's very spicy!)
