Umami Sushi is a small sushi restaurant in Greenwich Village where a weekday lunch can mean sitting by the window without waiting. The sushi deluxe and spicy tuna crispy rice are the popular orders, and the fish is repeatedly described as fresh. The space is decorated with fake cherry blossoms, and one complaint describes a staff member behaving rudely. Service can be slow, and the place suits solo diners or dates more than large groups.
