Thirteen has gluten free beer (Glutenberg) and some ciders. The wings are marked as gluten free on the menu, but I confirmed with the server that they are fried in a shared fryer with products containing wheat. I ended up ordering the nachos with chicken, and they were very good. They offer gluten free burger buns for an extra $2.00.
