It has limited ambience, no real seating, and the prices are higher than most of the nearby options.
However, the take-out sushi is better than most sit-down sushi restaurants, well prepared and well-presented in containers, fresh and delicious.
If you're looking for a pampered total experience, this wouldn't be your first choice, but if you're looking for top-class sushi that you can take away and enjoy at home, there's no better choice in the city that I've tried.
