This is the best sushi in the area and I know this because I've been to all of them. Owner Yoshi came to the capital district about 10 years ago. He started working at Ginza (which is now gone) and then opened his own place in a plaza on rt9. It is quaint with only a four tables and a sushi bar and not particularly beautiful inside, but the sushi is ALWAYS top notch. I care less about what a place looks like to its quality of food.
The sushi is never old, ALWAYS fresh and eight out of ten times you could slice the tuna with your tongue its so tender. Lets face it, good sushi really is all about the fish, and Yoshi obtains and prepares it correctly. His hand rolls are also very interesting - in particular ask him for a spicy salmon hand roll (its not on the menu).
The prices are very good, especially if you arrive for lunch. There is a filling $6 lunch box that comes with soup and salad. The dinner box is equally a good deal. You are generally automatically served soup and salad with any meal.
Overall you really couldn't ask for more. Excellent food, well prepared and not expensive. The only down side is perhaps that they don't have a liquor license, but Yoshi doesn't mind if your bring your own bottle. This is one of my top five favorite restaurants in the area. I eat here weekly. DEFINATELY go check it out.
