Fat Heads Saloon was the first place we eat out at after moving back to Pittsburgh. The entire 18-hour drive back to Pittsburgh my husband talked about Fat Heads' wings. Our first Monday in Pittsburgh, we headed here for wing night. Unfortunately, their wings on special are not gluten free, but I was able to order the whole wings which were gluten free.
The Fat Heads original sauce is a good enough to drink (or at the very least douse all over your meal). They have a great selection of drinks and food, but we seem to venture here more for wings than anything else.
