There are quite a few choices, Rosie, depending on what your children enjoy. Both the Nascar Cafe and NBA City are heavily sports-themed diners, with loads of games, videos, etc. Jimmy Buffet's Margaritaville is a nicely-themed choice early evening (later on it gets a little loud for chldren, IMHO), and the Hard Rock Cafe here is just HUGE (although, if you go to HRC's elsewhere, you might want to try one of the other choices). The Motown Cafe is a similar music-themed venue to Margaritaville.
You might also get some more opinions on the Universal Board, too.
I would take them to the Latin Quarter...outstanding food, great atmosphere..and the music and dancing (small shows) throughout dinner is a nice perk. The other children in the restaurant when we were there seemed to be enjoying it.
