The single finest, private, most luxurious sushi experience I've had in my life.
It's my platonic ideal of what a night over sushi should be.
Ginza Kyubey is probably the best and most famous sushi restaurant in Tokyo without a Michelin star, with a history dating back to 1935.
Great vibes, fantastic service, tourist friendly (although you'll need a hotel concierge to book you a reservation, like most of the best places in Tokyo).
I've tried to visit here with colleagues or friends every time I've been in Japan for the past decade or so. Always worth it, plus the Ginza is a fun neighborhood to bounce around in at night after you're done.
S/O to lisaluvspizza for the inspo.
