This tiny dining room in Tokyo’s Ark Hills district is unassuming, but inside you’ll find some of the best sushi in the world. This 3-Michelin starred restaurant is headed up by Chef Takashi Saito, who pays exquisite attention to things like texture, temperature, and flavor balance. It has only eight seats, so it’s absolutely critical to book well in advance. Its minimalist design features a sleek wooden bar and minimal, traditional Japanese decor. Lunch will run you between ¥5,500 and ¥17,000 ($50 to $150), while dinner can be ¥27,000 ($250) and up per person.
