This is my favorite place to eat in all of DisneyWorld, because of the little mice Suzy and Perla

It's an all you can eat and drink meal ( save stuff such as wine ) and it's $28.99 for adults and $12.99 for children ( or it's around that price )
Now I am a Vegan, so I am not sure if I can help you out by telling you how much I love the food there. But many meat-eaters have said that the food is really good there and I find the Vegan food to be really good there, so maybe that will give you an idea
The characters that are there are the Fairy Godmother in the lobby and the characters that come to your table are Cinderelly and her Prince and 2 female mice from Cinderelly called Suzy and Perla

Once in a while the Fairy Godmother has not been there and one of more times I have not seen the Prince there and someone like Princess Aurora would cover them. Also at times even when all the characters for the 1900 dinner were there someone like Alice or Princess Aurora was still there, but this is rare. Alice is pretty much always at the breakfast of 1900 Park Fare
If you have booked a meal at like around 4:30 p.m. or 4:50 p.m. maybe you could try to get there before 4:30 p.m. , because the way they open the dinner at the 1900 Park Fare at 4:30 p.m. is really cool

Also if you booked a meal later you might want to check to see if all the characters will be doing photos with guest in the lobby at around 9:10 p.m. or so.
Here are photos of me with the characters from the dinner at the 1900 Park Fare
