chef mickey's would probably be fun for the kids. lots of great character interaction. and we enjoyed our food for dinner, as well.
i love the 50's prime time cafe (as my siggie states) because it is so much fun. the waiters make you keep your elbows off the table, and it's like you're back in the 50's, finish your veggies, etc. as long as you want to play along, that's a great one.
also at the studios is sci fi, which is very well themed, they have sci fi shorts playing, and you get to sit in cars to eat. i've heard if you stick with the burgers, onion rings, and shakes, that the food is good too.
that's just a few. i'm sure others will suggest more.
