This. deserves a separate post. The Standing Sushi Bar in Shibuya, a tiny little place just one block from my office. On the hunt for a cheap lunch, this was recommended to us by a work mate and it was really amazing sushi for a really good price. Freshly made in front of you, by quite nice and funny sushi chefs, I was told by my Japanese work mate, who went with me there.
But see for yourselves.
