Tried Oiishi for the first time this past Saturday. (had attemted to go a number of other times but the lines were always much too long). This time we went early - probably around 4:45-5:00 and got in just in time. Within minutes of taking the last 2 open seats at the bar, the line stretched out the door.
Oiishi is incredible...clearly the best sushi restaurant in the area. We didn't stray too far from the usual on our first visit - stuck to the sashimi (yellow tail, tuna), maki (spider roll, spicy tuna), seaweed salad and an excellent grilled squid dish. It was all exquisitely prepared with large slices of fresh fish and beautiful presentations. So good. Can't wait to go back and try some of the more "exotic" choices on the menu.
