Sushi Waka is an authentic family run Japanese restaurant located in Camden Town, London. The Sushi Waka website explains that all dishes are made by "Japanese chef and served by Japanese waitress. Sushi Waka is pure Japanese traditional restaurant".
I've booked for 12 people which would be enough to secure their upstairs room which is traditional, tatami-matted, and so we'll need to take off our shoes... So, don't delay, sign-up, and make sure no holes in the socks ;-)
There is a small, 1 pound per person, non-refundable, event fee to help towards organiser MeetUp fees and incidental costs.
