There is 1900 Park Faire at GF, Chef Mickeys' at Contemporary and Cape May at BC. There may be more but these are the only ones that come to mind.
I think there is something at the Swan/Dolphin too.
We enjoyed O'hana at Poly. Mickey, Lilo, and Stitch. It's a family style restaurant, so they bring platters of eggs, potato, bacon, pancakes, fruit, etc to your table. Really good.
1900 PF at GF has different characters for Breakfast (Mary Poppins and some others) and Dinner (Cinderella, Prince Charming, Lady Termaine, and the step sisters).
