The waitress said that there wasn't anything gluten free to go on the gluten free bun. She said that all she knew was that they had a gf bun. I chanced it and ate a ham sandwich and didn't get sick. I wouldn't have normally stayed to chance it but I had a toddler that I didn't want to haul somewhere else. If they offer a gf bun it would be greatly appreciated if they knew of the seasonings on the burger or ham for the sandwich were gf also. Very disappointed.
