Help -- Last minute dim sum in south bay
Ocean Seafood in Chinatown is only a 20 minute ride from the south bay on a sunday, but if you drive just a little farther to SGV and Sea Harbour you can't do better.

Now if it's ramen you wanted that's another story....
With three 14 year olds, my suggestion would be to try Grand China Buffet on Hawthorne in Torrance. They could choose whatever they personally like and there is a limited choice of dim sum (not of the best quality) but the variety is endless for other things. Plus, lunch is pretty reasonable.
