This is a pretty generous 4, as I feel it should be more of a high 3.
The ambiance/atmosphere is fitting of that of a fancier sushi restaurant with professional servers. I got the sushi set for $30, which had 12 pieces and 3 maki. They did include uni as part of the set which you don't usually get at this price point which was a nice surprise. However, the quality of the fish was mediocre.
At the end we had a small slice of complimentary cheesecake, probably because we came pretty late close to closing time - free food definitely makes me happy.
Overall a positive experience.
