If you're looking for a quick sit-down sushi place with incredible value, this is the spot for you. I come here with my girlfriend about once every couple of months when I'm craving a cheap bento box.
I usually come for their lunch-time prices. The best value, I find, is their combo-bento boxes where you can have any combination of tempura, teriyaki, sushi, or sashimi.
For the most part, you get what you pay for. The food isn't anything too exceptional, but it hits the spot when you're feeling hungry. They serve complimentary appetizers and green tea ice cream with your meal. I've never had a problem with their service but I only come during low peak time hours.
Overall, I would recommend sushi one to anyone that's looking for cheap sushi to fill their pallet.
