I've been to several different locations in two states, and the freshness of ingredients and consistency of food and service are very high. They somehow seem to get the reddest tomatoes for their condiments, too. I love their steak burritos, but often the meat is burnt. Sometimes they overfill the burritos with cheap ingredients like beans and rice.
Pros: fresh ingredients, generally healthy foo, clean
Cons: burnt meat, occasion.
