I like the Cannery, Svelte (In Corona Del Mar- small place, very swanky. there is a patio in the middle of the restaurant that has a bed, etc)and three thirty-three - it's brand new and seems to be the most happening place in NB.
I also give a strong recommendation to doing a duffy boat excursion. you can rent them in Newport Harbor, load up on drinks (non alcoholic for you of course) and appetizers and cruise around for a couple of hours. There are CD players on the boat. It's so much fun!
