No separate gluten free menu available, but we were assured ALL of the sauces were gluten-free and the fries are cooked in a dedicated frier. I ordered a burger with gluten-free bun, and fries. Everything was delicious, and I feel confident I wasn't glutened.
If you're on the fence about which burger to get, try the Original -- there's a hint of cinnamon in their "original" sauce that adds a unique twist to a traditional burger.
