We’ve eaten here twice, and none of the 5 celiacs have gotten sick. Menu isn’t marked GF but it’s huge, and they are willing to swap corn tortillas for flour in many, if not most, dishes, so lots of variety. Very friendly attentive staff, good basic Mexican food, great for a family or large group. Not sure I’d eat chips if you’re really sensitive, just to be on the safe side, but all-in-all a good experience and recommended!
