I'd give zero stars if I could. If you have a wheat or gluten allergy, don't eat in Flagstaff, AZ. They do not follow safe food handling procedures for allergies.
The person who does their fry station also handles wrapping up the burgers. They go from touching burger buns (wheat/gluten) with their gloved hands and without changing gloves, go to the uncooked fries and scoops them up and sticks them in the baskets and fries them cross-contacting all the fries and the fryer oil with wheat and gluten.
The manager on duty proceeded to state this how they always do their fries. Insisting incorrectly the fry oil at 350 degrees kills the allergens. Heat does does nothing to kill allergen proteins, just keeps them in circulation.
Don't risk your health or your life eating here if you have food allergies and don't buy the hype on their website, they have zero clue about avoiding cross-contact.
