Caroline, thanks for such a great question. Dining at Walt Disney World is one of my favorite activities, and being able to dine with just my husband would be such a treat. You are one lucky lady! I have a couple suggestions for your night out!
Flying Fish Cafe is one of Disney's Signature Dining locations and is found on Disney's Boardwalk. It is a fun-filled restaurant that serves some of the best seafood I have ever tasted. For a one of a kind experience with your husband I recommend the Chef's Tasting Wine Dinner. This is a five course menu paired with some lovely wines. Reservations are recommended, the dining event takes place Sunday through Thursday at 5:45 PM and again at 8:15 PM.
Monsieur Paul is a gourmet restaurant located in the France Pavilion of World Showcase at Epcot. If you are looking for a romantic setting this is the place to be. Not only will you find fine French wines and classic cuisine, you will find a view of Epcot that will take your breath away. (Be sure to request a window seat upon arrival. You may have to wait, but it will be worth it.)
Enjoy vacationing with your Prince Charming, I hope all your fairytale wishes come true!
