The only thing fried in the fryer is french fries. Both the regular and sweet potato fries are gluten free. The manager and all employees are very good about asking if it is an allergy and will clean the cook top or use foil. If they don't know if an ingredient is gluten free the manager has gotten out the product and let me look at the ingredients list. I have eaten here many, many times over 4 or 5 years and have never been glutened.
