My kids (10 and 8) love the character meals, we have done all of them except for Hollywood and Vine (kids don't watch Disney Jr). Our favorite character meals are Cape May Cafe Breakfast, Crystal Palace Breakfast, Akershus Breakfast, and 1900 Park Fare Breakfast.
The non character meals that my kids really like are: Sci-Fi, Mama Melrose, Tony's Town Square, Liberty Tree Tavern Lunch, and Whispering Canyon Cafe
The QS restaruants that they really like and we have to do at least once a trip are Pecos Bills, Columbia Harbor House, the QS at POFQ, and Beaches and Cream.
They also love 2 Signature meals...California Grill and Artist Point.
