actually had a very same experience as Hampy.
At best this would be a very, very average sushi place - kind of that one might walk in if in a hurry during lunch in a city never visited before. Tartar appetizer was the only one worth mentioning. Most of the dishes were way too salty, size wise they were okay though. Quality wise, to my astonishment, sushi were really bad - stale very gamy fish, sashimi not much better.
Ambiance - well, it's an eatery and not a chick one either. Very crowded space (try to get one of the booth tables on the window sides). If you end up sitting on the middle it is likely you'll be pumped into a few times by wait stuff or patrons...
Don't think that the stuff was pompous though certainly they could have been more attentive for the price.
Given choices of the really good downtown restaurants in NY this would be certainly not one of the places i'd ever suggest anyone to consider - one star...
