Most of the taco ingredients here are gluten free, as long as you go with corn tortillas. We specified gluten free in the kiosk ordering system for my son and a staff member came over to check with us about the breakfast taco potatoes he'd selected, because they're cooked in the same fryer as their churros. We opted out of the potatoes and everything was great. Plus, the tortilla chips have a dedicated fryer!
Their online menu has good info about gluten and allergies.
