You might want to consider Cinderella's Royal Table. You can't beat the atmosphere. Here's a write-up from allearsnet on the dinner that will be in place after Feb. 1, 2006:
"-- Dinner will become a fixed-price, set meal, also, hosted by the Fairy Godmother, who will lead the observance of special occasions like birthdays and anniversaries. You will also have the chance to have your photo taken before dining, with a photo package similar to that mentioned above offered to you during the meal. In addition, you will receive a special, unframed, unmatted lithograph (worth $50), given exclusively to diners at Cinderella's Royal Table Dinner. Dinner: $39.99 ages 10 and up; $24.99 ages 3-9."
