I went last summer and they DID have a gluten free bun for a gluten free veggie burger! Not a “roll” if you get a lobster roll, although they may have that and worth asking. But my burger bun and veggie burger were great, had it with fries and Cole slaw and able to enjoy a lovely dinner on the vibrant patio. Right on the water, with tables under tents and heat lamps for chilly evenings. Live music outside and limited seating inside. It’s very “Maine”. They also do offer salads, for lighter gf options. Not sure about a separate fryer for fries, though
