Burgerfi is a grass-fed burger joint. They do not have a gluten free bun, but they do have a lettuce wrap instead of a bun. They are definitely NOT knowledgeable about what gluten is. I came in hopeful and the workers told me everything has gluten and they just tell all customers that everything has gluten. We asked them if there is anything inside the meat and of course they said no, it's just meat. Then we asked if they know what gluten is and of course they said no. They really should educate themselves instead of turning away customers. I almost left, but luckily I am very knowledgeable and know the right questions to ask. We ended up having to talk to the manager, and he was more educated. They cook the burgers in peanut oil and it is cooked on a separate grill than the buns. The basic burgerfi burger and the veggie burger are gluten free (the veggie burger is made with quinoa). I had a burgerfi burger wrapped in lettuce. There was more lettuce than meat, but it was good and I feel fine!
