Chipotle is fast food yet it doesn't quite feel that way. Everything is prepared fresh and there are enough vegan options to please one's appetite. Funny that it's location is directly across from a Taco Bell because they couldn't be more opposite. Sofritas (organic tofu shredded and braised with chipotle chilis, roasted poblanos and spices) guacamole, black and pinto beans all make great options for vegans and vegetarians when looking for something quick and inexpensive.
Cons: serves meat too, inconvient traffic rules (no left turn)
