Conveniently located in the heart of Tokyo — B1 °F of Shinmarunouchi Building, this place is great spot for grabbing quick«Chazuke”( ) lunch. They have quite wide range of variation(snapper, salmon, chicken and veggie) for stock you can pour it over. Beside chazuke, it comes with pickle veggie and very, very delicious tofu flavored with sesame miso sauce over it. Avoid noon to 1pm on weekdays. But the line rather moves quickly so it might be ok even if you come during that time range. Stock is flavorful and gentle especially I’m suffering from hangover. They are pretty generous with topping(Had salmon today) as well. It’s quite popular among ladies but good meal for men as well.
