We went to the one in the San Francisco Shopping Center 5 years ago for my son's 2nd birthday party and that bear is still my son's favorite. My 4 year old daughter went to a drop off party here today (there were a few adult relatives for the 20 kids, but the staff seemed to take it in stride). I think 2 was a little young for them to get a lot out of it and it was somewhat expensive (when you have a party here, you hate to disappoint the kids and stick to the basic bear, which is reasonable, so you end up spending about $25/kid), they do have great staff members and you don't have to worry about party favors. The downside is that they don't have a room to have cake, so you have to retire to either the Boudin (which isn't equipped to handle a party for young ones or CPK or buy food or drink at the food court to serve cake. The birthday kid gets an autograph bear and a birthday CD (you'll want to smash it with a sledgehammer before long, but your kids will love it).
