Sakagura

If you don't know exactly where this place is ahead of time, it's impossible to find it because it is in the basement of a house with no visible signs on the outside. To get to the restaurant, you have to go through a gate, pass reception and down the stairs that seem to lead nowhere. But, when you pass through the door, you reach an amazing space with around 150 seats spread out in various rooms. At the entrance, you'll find the bathrooms located in these giant wooden barrel type things, with 100% Japanese toilets will all the buttons and hi-tech flourishes. Once you get to the restaurant, I'd suggest a tasting menu with a variety of sushi and sahsimi.
