Hi Valerie:
While many of the younger guests may choose to dress up as princesses while dining at Cinderella's Royal Table, there is no dress code.
If I had to select only one "date night" restaurant at Walt Disney World, it would be
California Grill atop the Contemporary Resort. California Grill features delicious California Fusion cooking and spectacular views of the Magic Kingdom and the Wishes fireworks show. If I could throw in three close runner-ups, I would also recommend
Le Cellier, a tasty steakhouse at Epcot's Canada Pavilion,
Jiko at Animal Kingdom Lodge, which serves dishes influenced by African, Indian, and Mediterranean cuisine, and
Victoria and Albert's, a winner year-after-year of the prestigious AAA Five Diamond award.
Enjoy your vacation and date night.
