This is my DD's favorite breakfast spot in the World (she's 5). Both times we've been there, Mary Poppins has been there. The food is, as has already been stated, standard (but tasty) breakfast buffet fare, but the made-to-order omelettes are superb and the bread pudding is delicious.
This past May, we were surprised to find Cinderella at breakfast when we went - DD was never really a huge fan of any of the princesses, but she was pretty impressed meeting Cinderella, especially when she wished DD a Happy Birthday.
All in all, it's a favorite breakfast spot for all of us!
