Atmosphere is amazing and transports you to another world. Extensive drink menu, but the tapas are good too. Try the broiled eel, not too sticky/sweet like others.
Nice and pretty authentic Japanese atmosphere. However the service was one of the worst I've experienced in New York. I'm sorry to say this but the waiters have to learn English and drop the attitude.
Underground, amazing sake menu, good for a date. Food is not stellar; it's for drinks and atmosphere. Order a cold, dry sake off the specials menu and enjoy a long conversation.
