There are many good restaurants in the deluxe resorts, including the resorts in the Boardwalk area. They are generally better than most of the restaurants in the parks, with perhaps the restaurants in the World Showcase at Epcot. My suggestion would be to check out the menus on the WDW website and see what appeals to your family. You might consider Kona Cafe, The Turf Club, Kouzzina, Boma, The Wave, and The Grand Floridian Cafe. The signature restaurants are also quite good.
