Fire on the Mountain (FOTM) has become a staple part of my gluten free diet in the last year or so. Their wings are amazing and only two of their regular sauces have gluten in them. Also, all of their sauces are labeled with gluten free or vegan/vegetarian. While the gluten free vegetarian or vegan might have trouble finding food options (their vegan wings do have breading), it is a great venue for groups mixed with various dietary concerns.
