Time Out says
It certainly doesn't look like much, but this spirited little sushi shop under the tracks at Gotanda Station serves up unbelievably tasty fare at reasonable prices. Go for the nine-piece set (¥800) for a quick bite, or dine in style with the special nigiri set (¥1,600), which comes with a maki roll and provides serious value.
UPDATE: Tsutsui has closed permanently.
