Hi Melissa,
How lucky are you to be celebrating your birthday at WDW! I think the
50s Prime Time Cafe is an absolute hoot to dine at with children, especially for a celebration. The cast members are so much fun there as they remind you to keep your elbows of the table and to clean your plates.
If you'd prefer something more toned down,
The Hollywood Brown Derby has delicious food and the feeling of the Golden Age of Hollywood, but is still appropriate for children. In fact as I began planning our next trip, it was the first restaurant my husband wanted me to include in our dining plans.
If you'd like to celebrate your birthday with Disney characters, the
Garden Grove at the Swan Resort has dinner with characters. The restaurant is just a boat ride away from Disney's Hollywood Studios.
And did you know you can order a cake to celebrate your birthday? For more information, you can call 407-827-2253.
Have a great trip; please let us know if we can help again.
