Bought a Groupon here to try it out, and decided to buy another because we knew we'd come back!
Go for dinner, sit outside, and enjoy an amazing view of downtown, something you can't really get from many uptown restaurants. Views of many buildings, but set back from the street, just a really great location for evening.
Sushi: they have interesting rolls like ones with sweet potatoes that I've never seen any where else. Really yummy sushi of all types.
Drinks: really good mixed drinks and sake! Limited wine and beer.
Service: Truly excellent!
