I remember posting some photos on here a while ago about our experience there....let me see if I can find them....

If I remember correctly, we were not at all impressed with the food. The characters were OK, not Disney of course, but the boys liked Spidey and the Grinch.
IMHO, I would say go for it if you all like the characters there, but don't expect Disney quality food cause you will be disappointed.
I can't remember the reservation system there. We just walked up and got in for breakfast. It wasn't crowded at all. (You can see how few people were there in the second photo) I guess it depends when you go. I do think they have a system you can call ahead, but we just did it while we were there.
