Hi Kim! Wow, choosing just one restaurant among all the great options is a tough choice so I will share some of my favorites and why they are my favorites. Being that you are all adults I will concentrate on those that offer a somewhat more sophisticated atmosphere and menu.
The finest restaurant on property is
Victoria and Alberts located in the Grand Floridian. It is adult only and jackets required but it is a real treat for a dining experience. Other fine dining choices include
Citricos in the Grand Floridian and
California Grill in the Contemporary resort.
For a relaxed and hand clapping experience try the
Hoop Dee Doo Musical Revue in the Fort Wilderness resort. This is a dinner show and although the food is basic it is good and the atmosphere is fun.
Park favorites include Teppan Edo in Epcot and the Brown Derby in Hollywood Studios.
You can check out all dining options
HERE. You can read the descriptions of each and check out the menus. Disney Springs has many new dining choices and my favorites so far include the Boathouse and Morimotos. There are many great options and picking "the one" is going to be tough.
