I would rate Kiu 3 stars, plus another 0.5 due to great service from our waiter.
Came here on a Saturday night to catch up with some friends. We didn't have a reservation so had to wait a good half hour before finally being seated. Unfortunately the host at the front was not the greatest and for some time had forgotten to seat our party. Also when we were brought inside we noticed that there were quite a few empty tables (some without reserved signs) so didn't understand the need for the long wait.
We ordered the chicken karaage, an appetizer set with nine different items, the red miso ramen, and the white sesame shio ramen to share amongst the three of us. I particularly enjoyed the appetizer set which contained various Japanese side dishes such as tako wasabi, grilled unagi, and beef tataki. The portions are very small but still recommended for sharing. The chicken karaage was tasty too. Both ramen dishes were disappointing, which is unfortunate as that is partly what they are supposed to be known for since they also own Ramen Isshin. The red miso ramen was too salty while the white sesame shio ramen was kind of bland. My friends also tried the black sesame cheesecake which was average.
If I ever come back, I would probably just order their appetizers.
