Sushi Wave has the best sushi I've had in O.C. There is often a 20 minute wait. It's funny because the place is full of Americans instead of Japanese natives even though there are lots of Japanese natives in the area. At least most of the employees are Japanese natives. What makes it so good? The fish is fresh!
Directions: From the 405 south take the 73 to the 55 south and then exit the 55 and drive down Newport Ave long the side of the freeway. Sushi Wave is on the right in a strip mall several lights down. If you make it to NikeTown and Triangle Square you've gone 1 or 2 lights too far.
