Not including counter service...
1. Le Cellier: This is a steakhouse in Canada in Epcot. While children do go here, it isn't the same atmosphere as kid-friendly places to eat. In other words, make sure your kids can sit still somewhere nice.
2. Chef Mickey's: A buffet in the Contemporary resort with characters (Mickey, Donald, Goofy, Pluto). They do breakfast, lunch, and dinner.
3. Sci-Fi Dine Inn: Great place for lunch in Disney Hollywood Studios. Decorated like a drive-in theatre, with a movie screen showing previews from 50's sci-fi movies and sci-fi cartoons. And you eat in a booth shaped like a car.
