Whenever I go back to the US, I seek out a burrito shop. I just cannot get any decent burritos in Montreal, which is ok because you can get pretty much everything else in very good quality. Anyhow, where I do usually go: Chipolte's. They have reliably tasty stuff. And now, I can feel better because they have a snazzy ad campaign:
Yep, the burritos are sustainable. Well, sort of--I will keep buying them. How about you?
