4.5 if they had more staff on busy nights.
We had a reservation for dinner on a Friday night. Relatively small-size restaurant with 4 waiters which sounds reasonable but only 2 of them took orders. Fortunately they provided good service and only forgot about one of our orders.
The sweet shrimp was excellent in size and quality and made the price worth it. The salmon and beef sashimi were above average quality and the rest of the fish was average quality. The handrolls weren't bad with a minimal amount of rice inside. They have about 9 different variations of maki rolls. The two I tried weren't great but they gently filled my stomach. There was a wide variety of tempura but it was only about average. The hot food was mostly pretty good. The steak with garlic was made perfectly medium rare. One complaint is that the portions of noodles (udon & ramen) are too big for an AYCE, meaning you won't have as much room to eat other things. The dessert options were limited with ice cream, mango pudding and jello. The pudding was delicious. The jello...not so much.
Please note that you will be charged 5% more if you use any form of payment other than cash. A service charge of 12% will be automatically added to your bill. Seating time is limited to 1.5 hours but they never asked us to leave even though we went over the time. This is all written in the fine print on the menu. Personally, I don't think any of these conditions are dealbreakers but they might be for some folks.
I agree with the other reviewers in that the quality of the sashimi makes this place worth going to. The selection of the hot food impressed me too. Can't wait to go back to eat more of their sweet shrimp.
