Well, then go to the restaurants in the Swan and Dolphin. They are expensive, but according to sources have the best restaurants such as Blue Zoo and Shulas.
At the other resorts, 'Ohana, The Spirit of Aloha show or Hoop Dee Doo Revue Show are nice for couples.
Crystal Palace if you want to get close to the Pooh characters either breakfast or dinner.
Be Our Guest ( tough reservation to snag still
)
Chip N Dale's Garden Grill ( very fresh food and family style all you can eat)
Any restaurant in EPCOT, depending upon your tastes.
Hollywood Brown Derby
Splurge and eat at Victoria and Alberts at Grand Floridian ( or any Grand Floridian Signature restaurant)
Flying Fish Cafe on the Boardwalk ( that would be an easy walk if you're at the Dolphin)
I think they still do Mickey's Backyard BBQ at Fort Wilderness ( always a fun time if you like BBQ)
It really depends on your budget. If you don't have one, then I would suggest all of the signature restaurants. See allears.net for dining menus and such.
Have a great time, and welcome to WDW!
