O-Ku

O-Ku is the South Boulevard sushi restaurant and lounge in South End, from the Indigo Road group. It is a special occasion room with fresh, inventive sushi, wagyu nigiri and a hot kitchen turning out duck buns. Birthdays are a specialty here, and staff have found personal gifts to match a note left on a reservation. The room is polished and always full, which gives it the energy of an occasion even on a weeknight. Service is attentive and the kitchen sends replacements quickly when a plate runs late.
