I recommend Chefs de France or Biergarten. For CS I recommend Tangierine Cafe and Kringla Bakerei or Boulangerie Patisserie. If you are looking for characters, the only character meals are Akershus and Garden Grill.
I highly recommend Le Cellier, it has to be the best place we've eaten at Epcot!!! But if you are looking for a character meal, the only ones are in Norway with the princesses, but if I remember correctly this does not include Ariel, I believe normally appearing are Snow White, Belle, Jasmine, Mulan and Aurora. The other character meal is Garden Grille and this has the Chipmunks.
My kids enjoyed GG when they were younger, also SAI.
Lately they liked LeCellier best, especially the kiddie desserts. They also love Teppanyaki although we eat dinner there. This trip we are trying Biergarten for lunch.
