The Palo Alto location definitely has better tasting food than it's sister store in Los Altos, however the seating is extremely limited (not that it takes long to eat a taco in the first place).
Sorry Chet, but the mini burrito is smaller than the chimichanga and is really only for kids. Good food, although nearly everything comes with cheese, so watch out if you're lactose intolerant.
They don't like you making "changes" to their "pronto special" even if those changes include removing an ingredient (cheese, for example). It's not like these are premade and ready to go, sheesh!
