I've only been to their location on New Montgomery Street and I have to say that I was really disappointed in my meal. I ordered the chicken burrito and my chicken was so blackened and charred that my entire burrito had a horrible burnt aftertaste to it. I couldn't eat it so I told the guy what was wrong with it and he looked at me like I was crazy. He did exchange my burrito for a vegetarian one, which was filled with pilaf and beans but didn't have much taste.
I think I'll stick to my mission burritos, El Farolito in particular. No comparision.
