While I agree with PP, here are some that my children really like:
1) ANY character meal: favorites are Crystal Palace, Chef Mickey's and Cinderella's Royal Table
2)'Ohana dinner - hula lessons etc...
3) Teppan Edo - they cook in front of you
4) Biergarten - they love the band
5) Coral Reef - has the giant fish tank
6) Whispering Canyon Cafe - stick pony races, hokey pokey etc...
Check out the menus and see what appeals to your family. We like to do a mix of buffet/ family style/ regular service and a mix of breakfast/ lunch/ dinner.
