Top Five TS (at this time, it changes a lot, and I am very narrowed by the requirement that the restaurant be on the dining plan)
Jiko
Kouzzina
California Grill
Sanaa
Flying Fish
Top 5 CS:
Wolfgang Puck Express (although I don't get there much)
Columbia Harbor House
Tangierine Cafe (on and off the list based on whether or not they serve me cold meat)
Sunshine Seasons
Captain Cook's (just for the adult grilled cheese. They get rid of that and it's off the list)
If you are going in a week, have a dining plan and haven't made reservations yet...you need to get on it if you want any in-park restaurants or character meals. The really popular places, you probably won't get.
