My daughter had the ribs, beans, corn, potatoes and was brought out gluten free cornbread and grilled chicken. She was offered strawberries and whipped cream for dessert instead of the shortcake. I think it depends on the chef.
Photos of our GF experience in my link, but the show was great. It was really fun! We had plenty of food, though they didn't offer a sub for the cornbread so we went without and the dessert option for us was only sorbet. I was a little disappointed they couldn't do anything more for such a special night, but it was still a lot of fun!
