I called them to answer this question. First things first, they take reservations and they are filling up quickly! If you want to go, make a reservation. They are offering a buffet from 11 a.m. to 3 p.m. Additionally it is $17 for children 13 years and under, and $28 for adults. (All of this information was accurate at the time of the call. Things may have changed since then!)

I do believe they have gluten free menu items, However I'm not sure about their buns

On the corner of "what is" and "almost there"! Your welcome
