Are you thinking about the Hoop Dee Doo Review at Fort Wilderness? It is an all you care to eat dinner.
The menu consists of salad and corn bread and butter, fried chicken, ribs, corn, and baked beans. There is strawberry Shortcake for desert. The meal includes beer, wine and sangria, as well as other beverages. It is very "Down Home" cooking and I think it is very good.
There is a western themed show with singing, dancing, piano playing and lots of corny jokes. If you like this kind of thing it is great fun. The actors circulate among the diner guests and there is lots of audience participation.
We enjoy it very much.
Other than holiday priciing (which is higher than non holidays), I don't know if they do something special for the holiday. I don't think so, but I could be wrong.
Have a Great Trip.
