We had a fantastic dinner there last year. If your PS is late enough, you get to exit through an empty Magic Kingdom! Way cool.
I had beef, DH had risotto (somebody oversalted and he had to send back, replacement was perfect and came out quickly). Salads were excellent, dessert was apple custard bread pudding I think (something like that). You can't beat the Castle for atmosphere, and our server was terrific.
Enjoy!
