As Japanese restaurants go, Nami is a solid B. I was visiting from Northern Cal where we have some of the most elaborate collection of Japanese restaurants, why with an entire Japan town neighborhoods in SF and SJC.
Nami was quiet, clean and very modern Japanesque in its interior design. The preparations were carefully done and had a few authentic Japanese items (such as Nato beans) which many mainstream restaurants don't care to carry.
Overall a comfortable place for business or family oriented gathering. Service is top notch.
The only reason for a three and not four star is coz I'm spoiled by having lived in N California.
