What are you looking for in a character breakfast?
I like Mickey's because Mickey is there (he's my favorite!!!) and because of the interactive surf dance show for the kids. My kids love it, and it is just fun to see all the kids having so much fun with the characters.
I like Storyteller's food best. It is the favorite of my parents and my 18 year old daughter. You can order off the menu or get the buffet. They have eggs benedict (I didn't see that any place else, but could have missed it...) on both, and if they aren't to your liking from the buffet, they'll make them to order and bring them out to you. My son likes it best because, at 3, he's still a little afraid of "Giant Mickey Mouse" and the other big characters, but he expects bears to be big, so he likes them a bit better.
My 8 year old likes Minnie's best because they have the most characters.
