Oishii has good sushi and asian food for a good price. I'd say they're better tasting than Sushi Boat across the street, but at a slightly higher cost.
The food here is good. The bulgogi bowls are cheap and a great deal, and the sushi is decent quality. Try the caterpillar roll - you won't regret it!
The inside of the place is clean and they have seating upstairs. Staff is friendly and you don't wait too long for food. Give it a try, you'll like it.
