Came here after reading the very helpful reviews. Getting off at Akasaka station on the Chiyoda line leads you right into the Biz tower. Checking the restaurant board, we found the restaurant's name in Kangei/Chinese characters so we found the restaurant easily on the 2nd floor. The line outside could have told us we were at the right place though. We signed our name on the waiting list and had a short wait despite it being 1pm on a Thursday. We sat at the sushi counter and our order was taken by the sushi chef himself! We ordered two lunch specials then an order of California roll and another order of the Norway roll (total around 4,360 yen! Great deal!) Everything was fresh and the maki rolls were quite big. My boyfriend had wanted to order eight pieces of each type of maki roll, but the sushi chef wisely only made four of each. He gestured to us that we would be too full and he was right! What great service!
