This topic might be better for the Disney Restaurants board

but I would love to suggest Yachtsman Steakhouse for dinner. Reservations ARE recommended, so maybe it is not what you had in mind, but it is a Signature dining experience and definitely well worth it! Also, you will be right around the Boardwalk area, so definitely check out Beaches and Cream (I don't think you need reservations). You can grab breakfast from Boardwalk Bakery, here is a review of some of the newer items:

Hurricane Hanna's offers lunch too! It is poolside, and quick service.
Good luck and have a great time! Yacht Club is my number 1 dream destination on property!
