I've probably been to this place about a dozen times and I still love going even though Blowfish opened up just down the street. The raw fish is very fresh and they even serve up UNI - sea urchin, a lot of Japanese/Sushi joints don't carry this. The Uni there is very fresh, which is immensely important since consuming not fresh Uni could have you stay away from sushi for a very long time if you catch my drift.
The service is quite prompt and friendly for small groups and large groups - I went there with 20 of us once for a function and they provided us a private dining area. Time your dinner carefully as you might run into the obnoxious patrons that come for drinks after work. Then it turns into a pick up bar with guys trying to tell you about their stock portfolio. I suppose that could be a selling feature for some.
