Review of Five Guys

They are great! Very friendly and knowledgeable about GF. Their fry sauce is no longer GF, they were nice enough to not only let me know this but also mix mayo and ketchup for me. You can get a lettuce wrap and they don't look at you weird when you tell them you have a wheat issue. I've watched them prepare my food every time I've been in there. They always change gloves and make sure not to cross - contaminate.

Celiac friendly?

Yes
