There's Pizzafari for Pizza and the Flamtree Barbaque has sandwiches, fries and platters. There's a place over by Kali River Rapids that have hotdogs, fries and other small stuff. Can't remember if they have burgers or not.
Hope this helps.
Restaurantosaurus serves McD's fries and nuggets, but does NOT serve McD's burgers. They serve the standard "Disney Burger" (basically the same thing you'll get at Electric Umbrella, ABC Comissary, Pecos Bills, Cosmic Rays, etc)
