Nob Hill is one of those restaurants which reaffirms my faith that Las Vegas is figuring out how to do great food.
If you're looking for a great date idea, stop in here either before or after going to see Ka. Be sure to allow time for a few cocktails before dinner, the signature drinks here are outstanding (I recommend ordering a cablecar). Now sit your butt down, order up the Prix Fixe and if you're going to the show be sure to tell them ahead of time.
Unlike at the tables, at Nob Hill you're going to come away a winner.
