I will throw The Boardwalk out there as well. There are multiple restaurants around there that are very highly rated and then you can choose to stop over at Epcot or Hollywood Studios for fireworks which are both within walking distance or you can just walk around The Boardwalk and enjoy a quiet evening with crowds being lower in that area or stop in at the dueling piano bar and enjoy some music after a great meal. The restaurants I would recommend near The Boardwalk are Flying Fish, Shula's (best steak on property in my opinion), Yachtsman, Il Mulino and Kimonos. It is also beautiful to see The Boardwalk at night and would be a great place for a romantic walk after a wonderful dinner.
