I would skip Royal Table, I've never had good meal there. (tried it 4 times) It's all for the atmosphere & eating in the castle. Breakfast was much better that dinner.
Kona (excellent)
Tried Yak & Yeti & thought it was very good.
Boma (one of our favorite buffets)
Chef Mickey's is good for buffet
Teppan Edo, if you like Japanese style
