I've noticed over the years that this place has switched owners numerous of times but they keep their name the same. Kaga By Ginza is a great Japanese place to eat at.
Food: My party usually orders in different visits as listed: a la carte sashimi, different assorted handrolls, rolls, eel on rice, tempura dinner, black cod dinner, and salmon belly, Their salmon and yellowtail sashimi are really fresh and they cut it into big thick slices. Handrolls are decent since they give you a good ratio of fish to rice. The black cod dinner comes with two black cods and lots of vegetables which I like a lot. The salmon belly is really oily though. Overall, the majority of food options is good and delicious.
Service/Atmosphere: The service is on point and they usually have two people working on the floor. It's been renovated for a while and the seats are comfortable to sit for a long period of time. When there are big groups, this place can become quite noisy.
Sometimes cellular service is pretty weak when you sit at the back area but maybe that is my own cellular provider's problem. They also have free wifi to make up for the lack of cellular service.
Finally, make sure to call ahead and make a reservation to avoid sitting in the sushi bar area as they are pretty busy on the weekends.
