The sign on the door says it all – everything except the bun is gluten free. We went here a few months back and I have to say that everything I had was tasty, the toppings, the fries (which are big portions), and the burger itself. Currently there are three locations in Columbus (Polaris, Grove City and OSU), with a fourth Easton location coming soon.
Please be aware if you or a family member have a peanut allergy as there are many, many bags of peanuts around the whole place.
So go and enjoy a burger and fries (sans the bun.)
