tiffsix...love, love, love your avatar as we are diehard Giants fans!
I guess I'm in the minority by saying we had a good experience here for breakfast. Though this was 2 years ago, it was the height of the Little Einsteins popularity and was really fun for my DD. The character interaction was awesome as well as the energy of the dancing, etc.
I agree the food is somewhat "institutional" but really for us, DD ate cereal and yogurt and a pastry anyway, so it was fine.
It was really cool to get into then MGM, now DHS first thing in the am.
I would say go for the experience, not the food and you will be fine if those are the characters your kids would have fun with.
