We went to Boardwalk Burgers in Clareview last night, it was fantastic!
I had a mushroom swiss burger w/ gluten free bun and fries, they have a dedicated fryer and most of their beef burgers are gluten free.
Seriously have never had a gf bun that was so good! Spongy and not dry at all! I don't know if I've ever had a burger that good. As well the price was very reasonable.
Definitely worth the visit even if your not celiac, very tasty.
