I'm a sushi snob. I am. Sushi at a supermarket? No way. I've eaten at many high end sushi restaurants, so I fancy myself smarter than the average bear when it comes to sushi.
I dig Nikko. 1) it's hip. You walk in and it's like you're in NYC. 2) The food is just damn good.
I've been here 3 times now since moving to Charlotte almost 2 months ago. All three times - just great.
I never get sake, so I can't comment on that. I got a martini the first time and have gotten Kirin draft every other time. Yummy.
The fish - I've never had a poor piece of fish there. It's all very fresh and is well prepared. Warning - they put a lot of wasabi on their nagiri. You've been warned.
They have some really inventive rolls. The crispy salmon roll is really good. The crazy roll (served in some sort of cocktail glass) is not good. Avoid at all costs.
All the staff have been very nice, although busy at certain points, so it's a pain if you need another beer. However - One waiter gave me a great tip about their tuna tartare - they put a raw quail egg on top. Ask for it without that.
Enjoy - this place is a keeper. I'll be there pretty often.

I had their tuna tartare a few days ago. I would avoid this dish. It's basically their spicy tuna mixture sans the spicy. More weird to eat it without a roll...
