Really depends which characters your kids know/like. Mine never got into Winnie the Pooh, so we've never done Crystal Palace. They love Chef Mickey, because it's all the "main" characters. We also like Tuskar House, but we don't do AK on every trip, so that's not always an option. We did Cape May Cafe breakfast last year and that was good, too. Again, it's the big characters - Goofy, Donald, Minnie.
Find who your kiddo loves to watch on TV and then find their meal!
