This place rarely gets mentioned on Chowhound, which is suprising. I've been about four times and was pleased each time. My friend and I once ordered some sort of sushi/sashimi platter, and I felt that the quality of the fish was very good--much higher than the Porter Exchange places. My dinner tonight was also good, though the unagi don was ordinary.
The menu is extensive and has lots of unusual items. The restaurant is fairly small, and there was a wait tonight (Thursday) at around 7pm (but the sushi bar seemed less crowded). Also they have delivery.
Here's a menu:
