Kaga is definitely a step up from Ginza. Still run by the same people but with an upgraded menu.
Here you will find fish flew directly from Japan arriving every Tuesdays and Thursdays if you want to have whole fish fresh sashimi.
Menu is covered most of what you expect from a more traditional Japanese restaurant. They also has Omakase starting from $50.
Lunch Special starting from $8.
Sushi Set ($10) has a good selection of fish. Quite a good value. The only complaint maybe the rolls were rolled too loosely and falling apart when picked up by chopsticks.
Staff is friendly and attentive. My tea cup was not empty.
Grand Opening 10% off with coupon.
