Lares in Santa Monica, California is the best Mexican restaurant that I have been able to eat at. Be warned, its small and busy during the lunch hour so try to get there during the off times otherwise you will have a hard time getting you questions answered. I have been able to eat at Acapulco's, but you have to ask a lot of questions if you want to eat there safely, starting with is the meat in a particular dish marinated and with what, and going on to what type of tortillas are you using today. There is an entire thread devoted to this restaurant. if you don't mind Tex-Mex, Rubio's has a lot of gluten free things on their menu and has allergen information on their web site. look at the bottom of the screen. I actually like their stuff better than most Mexican restaurants because I can eat there safely. Chipole's has gluten free stuff, but I have run into cross contamination issues there, usually I only eat there as a backup choice. I have been able to eat at most Mexican restaurants, but it pays to either speak spanish or go to one where the manager speaks english. I always have to ask a ton of questions. NO PAN = NO Bread. They sell these little cards in various languages that basically explain what gluten is and ask not to be fed it, these are really useful if you are having trouble being understood.
