I have just had sushi at Bluefin by Abe in the Crystal Cove shopping center in Newport Coast, and I must say that it is the best sushi I have had in southern CA, aside from Matsuhisa in LA. Bluefin is obviously very upscale and expensive, but the quality of the fish, the beauty of the presentations, the obvious skill of the chefs, and a full bar with an excellent sake selection, all add up to an outstanding meal. This is not inexpensive however. With a martini and a small flask of sake, dinner for one at the sushi bar cost me $115 (including tip). Interested to see if anyone else has been here and what their opinion might be.
