I came here in group of 5 or 6 for a coupon deal that I got. The coupon told us to make reservations before going which we did. When we got to the restaurant we had to wait for an incredibly long time before we got a seat.
Was the long wait worth it? Well, the food was good but it's not amazingly better than other a la carte or AYCE sushi places that I've been to. The service was great though but I got a feeling it was to compensate for the long wait we had to get a seat even with reservations.
If you live near a Ginza, go check it out, just not during dinner rush hour!
