Did DS5 birthday last May at 1900.
They give you a special laminated place mat with 1900 Park Fare, with all the Cindy characters and their autographs on the mat to keep.
Our Server and Perla (one of the mice) came over to sing happy birthday with a cupcake. We could have paid for a cake for him (I believe it was $20.)
All the characters came by and wished him a HBD: Cindy, Prince, Perla, Suzy (mice) and Fairy Godmother was in the lobby.
As far as the food, I found 1900 to be much better than Cindy's for bfast. The dinner buffet was really good, and the kids enjoyed the kids buffet. Breakfast in my opinion was just OK, you are definately paying for the Princesses at the Castle.
I'm sure you DD will enjoy 1900PF for her b-day.
