I always like Five Guys. I'm a Celiac, and it's a challenge to get a gluten-free burger and fries. They don't do fried food other than French fries, so those have safe for me to eat. I get my burger in their metal bowl with whatever fixings I want. They will do a lettuce wrap. Servers are friendly, and the service is usually quick. Plus, I can munch on peanuts in the shell while waiting.
