Review of Five Guys

Their burgers are so good and you can get them on a lettuce wrap, which I'm fairly certain they make on a piece of foil so there is no cross-contamination risk. The best GF fries too (although I'm not sure if the cajun seasoning is GF). As far as I can tell, there is nothing on the menu that they fry that contains gluten, so fries should be fine.

Celiac friendly?
