I used to live in the city and regularly went to places like Nobu, Sushisay, and Hatsuhana.
If you enjoy really good sushi and sashimi at reasonable (relatively) prices, I'd highly recommend stopping by Yuki. Since I've been going to them, I've stopped going elsewhere for sushi/sashimi.
Basically, it's high quality sushi, and highly consistent (i.e, I've never had bad or even slightly questionable food there)
The restaurant is BYOB and for a meal that is primaritly sushi/sashimi, you should expect to pay somewhere around $60-75 per person.
NOTE; This bill estimate is if you allow the sushi chef to order for you (commonly called Omekase). If you order your own on the menu, it will certainly cost less.
If you like Sushi and you live in Bergen or Rockland county, you are doing yourself a disservice if you don't try Yuki Sushi.
