Love this place! Went there for drinks the first time and they had cider and a small selection of gluten free beers. Just went again last night for dinner and it was so good! I had the bacon cheese burger on gluten free buns with side of French fries. Didn't get sick from it at all. Didn't try any of the bbq but they serve all they're bbq sandwiches on gluten free buns if requested. Will definitely have to go back to try more.
Update - Nov 2015: For probably the 20th time I have ordered the babyback ribs with BBQ sauce, baked beans and coleslaw. A meal that used to be safe to eat... Now having the worst gluten reaction I have had in a long time. Last time I ate at the Boneyard Bistro. Old 5 star review: Excellent BBQ - gluten free sauces, buns, main dishes and beer! Unfortunately a lot of the appetizers and sides are not GF but there still was plenty to eat. The taste was great!
All the BBQ is gluten free. They offer gluten free rolls. Unfortunately they do not offer a lot of gluten free sides. They are very knowledgable about their food and if they do not know the answer they will find out.
