Just went here with some friends tonight.
I had yellowtail nigiri, salmon nigiri and shoyu ramen.
The fish was the freshest I've had in the CU area, and I've been to Sushi Kame, Kamakura, Yellofin, Kofusion, you name it.
The ramen was also delicious, with very savory broth.
The ambiance of the restaurant was very chic, but not pretentious. Service was great and my table was waited on by the manager of the restaurant, who knew his stuff. This place would be excellent for a date.
A rule in life: you get what you pay for. If you want bad sushi with horrible rice, there are plenty of places to go on Green St., but if you want delicious sushi from a superb place, go to Sakanaya.
