I don't know if I would go as far as Jackie and place Nama over Japango but I will say that it is a great sushi restaurant with fantastic quality seafood and really great presentation. I always love finding a proper sushi restaurant with real japanese trained sushi chefs and this place is just that. They may not be the quickest in town but there is a reason for that, they focus on presenting a perfect dish every time.
Great place and worth a try
