Burgers ordered without the bun and the French fries are gluten free. I had caramelized onions & mushrooms, mayo, lettuce, and tomato on my burger. French fries are the only thing fried there so both the Cajun and regular fries are safe!! I asked for my burger to be made using clean gloves and I left without getting sick! My kids love five guys, my kids order hotdogs and they have peanuts out on the tables to eat.
