My kid's are 7 and 9 now. in the past they enjoyed Boma's (they love the mac n cheese and desserts)
Ohana's - atmosphere, my DS7 gets a hot dog from Kona's, my DD9 loves the menu!!
Sci-Fi - they like the atmosphere
Coral Reef - they like the tank
My kids don't actually enjoy the character meals anymore, except for Pooh and friends at Crystal Palace.
