I've eaten a good amount of their menu when I wasn't celiac. They have gf buns, but what really makes it worth the trip is the disco fries, so I can't really recommend it. But they make a decent burger and you can get a bun on it. (Can you have the fancy burgers with all the fixings? No. Will the waitress make you feel safe? Not particularly.) To be honest, I usually prefer getting Five Guys with a lettuce wrap across the street so I can get my fries, too.
