Ginza is a trap. It used to be good 2 to 3 years ago, but I've started to avoid this place since, in my opinion, they changed administration. The tempura is super oily and terrible, and the maki's are 90% rice, 9% ingredients, 1% seaweed.
I have been going to Ginza monthly back in the days, but it's no longer an option for me anymore.
To avoid if you are a true sashimi, nigiri, tempura and maki fan.
Although the service never changed, an all-you-can-eat sushi is about the quality of their food. No good food + good service = still not a good restaurant.
