had a chance to try Wasabi Sushi at 9th and 9th recently.
The fish seemed fresh with no hint of being old.
The prices were quite reasonable. I had two basic rolls and an order of inari and the tab came to just over $11.
I would recomend getting an order to go unless you don't mind sitting outside of in the rather small and cramped dining area. Only about 15 seats inside.
Didn't look, but in retrospect, I don't think that they had a liquor licence, so no saki here.

I still stand by my recomendation of Ginza near the salt palace, but if you are near 9th and 9th, this is some great sushi.
