I have been twice recently. The burgers are customizable, right down to the type of meat that is used! While they do not offer gluten-free buns, they offer a lettuce wrap. The fries are the only fried item, so no worries about cc there. But a heads up if you want chili cheese fries, the cheese sauce is not gluten-free. My most recent visit, I ordered a burger and added Swiss cheese and sautéed portobello mushrooms, tomato, pickles, and spicy mustard. I also ordered a large fry, which is large enough for 2-3 people to share. They have house made ketchup, which is really good with the fries.
