Hi Ran,
Yes the meals at Cinderella Castle do feature characters. Although you just asked about dinner I thought I'd list the other meals at Cinderella's Royal Table also. Please note that the characters listed are not guaranteed and do vary!
Breakfast and lunch may have Cinderella, Fairy Godmother, Belle, Snow White, Aurora, Perla, Suzy, Prince Charming and Jasmine.
Dinner is led by the Fairy Godmother so I would recommend going for a different meal if you or your child is interested in seeing lots of characters!
There is something so magical about dining in the Castle which makes this a very popular restaurant and I would strongly urge you to book reservations on 407-939-3463 at exactly 90 days before you start your trip. Also visit
www.allears.net select dining and then menus to see what food is on offer :)
Have a great stay,
Jo
