They have gluten free buns and their sweet potato fries are cooked in a dedicated fryer. After I paid $2.00 for the gf bun, they tell me they are out of gf buns. I didn't ask for a refund. The sweet potato fries were good, but they make their own ketchup and they told me it was not gf. It seems crazy to have gf buns and cook your sweet potato fries in a dedicated fryer and then make your own ketchup and put gluten in it.
