Every place that has been listed so far is cheap family style Chinese and no where you'd want to go for a date.
If you want to go to a classier place then go to Anqi at South Coast Plaza next to Bloomingdale's. For Dim Sum and a more "authentic" menu, but much busier and less stylish, then go right next door to Paradise Dynasty.
The food is terrific in both places
Check them both out.
