I'm a Boston chowhound in need of some advice--DH and I would to get his sister, who is moving to Newport Beach from the East Coast, a gift certificate at an excellent sushi restaurant in or near her future neighborhood as a Christmas gift. I've looked on Zagat and see that Abe and Wasa are supposed to be good--anyone have thoughts on these places, or know if they sell gift certificates? Or, are there other sushi restaurants, perhaps a bit further afield but worth the trip? I don't have a very good sense of the geography of the OC, or of how long it would take to drive from there to, say, a fabulous sushi place in LA. Any advice from local chowhounds would be much appreciated!
