Gluten free burger buns are available if you request them. Both my daughter and I react strongly to cross contamination and will order the burger without much reaction. The fries are not in a dedicated fryer, though, so be aware of that. They also have nice salad options. Still our go-to chain while traveling since they do have some options for our whole family.
