There should be a branch of this self-possessed little sushi bar/cafe in every neighborhood. It offers pristine sushi, as well as cooked items, including an array of soba noodle dishes. The menu contains pictures of a wide range of specialty rolls to help you make up your mind, or ask one of the diners sitting next to you for their favorite. Chances are it's not the first time they've been here — Sushi Ko makes a point to learn your name and order. L Mon.-Sat., D daily.
