Visited last week with 3 colleagues, and everything about the meal was wonderful. As we visited midweek, the restaurant wasn't particularly busy. The service was wonderful, and the food was incredible. The sushi in particular was amazing, although some of us also had soups, tempura and gyoza which were also delicious. Our meal cost less than £25 a head for the 4 of us, including alcohol, starters, and the service charge, which I thought was very good value. At the end of our meal the chef was kind enough to give us an extra plate of sushi on the house, which was incredibly kind and incredibly tasty. I thoroughly recommend Kisaku and will definitely be visiting again soon.
