As a Mexican living in Mexico, I really like chipotle, I eat one every time I'm in the US, they are the greatest mix of American and Mexican food, still I don't understand why there aren't authentic "Taquerias" (taco shops) in the US, I haven't met a foreigner that doesn't love tacos from our taquerias that you can find in every corner in Mexico City. The closest I ever tried was at a Taco Truck in LA, but that was just one food truck.
