A Japanese-inspired Restaurant by Chef Brian Lewis

Our menu celebrates Japanese techniques and traditions, infused with Chef Lewis’s signature culinary style. We use ingredients from local farms and waters in Connecticut and New York, from across the United States, and from the Tsukiji fish market in Japan. Our restaurants feature an open design that flows from the kitchen through the bar and into the dining room, creating an atmosphere where outstanding Japanese food and beverage come together.

Summer Mondays

Our Rye and OKO Westport locations are open for dinner on Mondays all summer long! Ease into the week with sushi, sashimi, hand rolls, tempura, craft cocktails, and all your other OKO favorites plus a few extra surprises. We can’t wait to cook for you!
