The only menu item explicitly noted as gluten free is the hamburger bun. They do have an allergen list on line, and there are very few gluten free items. The fries are made in the same fryer as gluten-containing items. The burgers are gluten free if you go with the gluten free bun or a lettuce wrap. Their special sauce (based on Thousand Island dressing) contains gluten, although the server was at a loss as to why. I had a basic burger on a gluten free bun and felt fine afterwards.
