Actually we are doing Kona Cafe! But you guys have sold me on SC - thank you so much for all of your helpCrystal palace IMO is a Golden Corral with Pooh characters. Since you're already doing two character meals, I would definitely go with the Skipper Canteen.
The shumai appetizers are on par with Mirimoto's.
Yet another option might be to hop on the monorail and eat at a resort, like Kona Cafe.
