There is always a small risk of cross contamination at a Five Guys because of the employees' gloves touching gluten but nevertheless it is my go-to for fast food and I don't think it's ever made me sick. The only gluten-free thing is the fries, but they're delicious, filling and the only gluten-free fast food fries from any chain I'm aware of.
