Chawanmushi, a savoury egg custard with a rich umami taste, is just one of the dishes you'll try at this secret supper club. Somewhere in East London you'll meet a bunch of strangers and sample a sumptuous menu crammed with contemporary Japanese cuisine. Menu highlights include: - foil baked shimeji mushrooms on soft tofu with ponzu - spinach in dashi marinade with katsuobushi - saikyo-miso marinated salmon The secret location will be revealed to you after booking…but we can tell you it's a 2 minute walk from Old Street station. Shhh.
