A very interesting question but yet the answers are somehwt dependent on the ages, etc of your party. All adult? with older / adult children or younger children.
1 - Best breakfast on property = Boma's Restaurant but the best breakfast in my opinion catering to children would be Crystal Palace. A close second would be Chef Mickey and then 1900 Park Fare.
2 - Non-Signature Rest - Well, LeCellier is out as it is 2 credits, Sanaa is out as well along with Jiko's etc. What is next? well, Chef de France is still the most consistently good restaurant to eat at. Rose Crown and Pub is also very good. For kids? well, that would be Cape May Cafe or again, Chef Mickey for dinner. Also, Whispering Canyon Cafe is excellent for ANY meal and there are games played during the hour you are there for the kids as well.
3 - Hidden but awesome gem.....Yak and Yeti Restaurant. Man, this place is scoring high as I have eaten there 4 times thus far and all my meals (lunch) have been awesome with great service as well.
Here is my list
1 - Chef de France
2 - Boma's Restaurant
3 - Yak and Yeti Restaurant
4 - Whispering Canyon Cafe
5 - Crystal Palace
