Like others mentioned, there isn't really anything spectacular about this place.
The food isn't terrible, but also not outstanding. For lunch, they have a small selection of specials, which include miso soup and salad. We ordered the sashimi lunch, which included 6 pieces of sashimi and 6 salmon (or California rolls). We also had the kento box with teriyaki, dumplings and California rolls. Each meal was $9.99.
The chicken teriyaki was pretty bad. In fact, I'm not sure where the pieces came from on the chicken...it was chewy and tough, so it got put aside.
Service was very fast - obviously, not a lunch hot spot - and waiters kept close attention to our green tea/water refills.
Price point is a bit high when compared to others and nothing really spectacular stands out about Kuni sushi - maybe will have to try it again for patio seating in the summer.
