Sunshine Seasons is great for breakfast after a run to get Soarin' fast passes when the park opens. Quick and easy.
Flame Tree BBQ in the Animal Kingdom has great pulled pork.
Cosmic Ray's is fun, but the food is pretty mediocre. The ribs are just not good.
My family's favorite, however, is Pecos Bill's Tall Tale Saloon! Fun decor and a surprisingly good chicken wrap. The cheeseburgers are quite good as well, especially with all the toppings at the topping bar. Sometimes on a busy evening a CM will pop in and hold a trivia contest or a "Yee-HA!" contest.
