Five Guys restaurant chain is always awesome and I have never gotten sick no matter the location. Huge bonus - you can est the fries! Fries are the only thing in their fryers so they are Gluten Free. You can order a burger either lettuce wrapped or unwrapped and add all your wanted toppings. When ordering tell them it is for a gluten allergy and they take it very seriously. They take all proper precautions to help minimize any cross contamination.
