My three lady friends and I had help from a promoter/host in getting in to Noir. It really is a nice change of pace from LAX, PURE, etc... If you can get in at least once, I say go for it! Inside, you'll find decadent, sexy decor - it's a little goth-y, but hot goth-y, not scary, Marilyn Manson goth-y. Deep colors on the walls and furniture, dim lighting, and crystal chandeliers make for a really chill atmosphere if you want a break from the crowds. You can lounge on the ample seating if you choose (and you know sitting is rare commodity in any Las Vegas venue!) with your $18+ specially-made cocktail. Yes, the drink prices are outlandish, but you get what you pay for - the strawberry concoction I had in a martini glass was phenomenal!!!! And the service was sweet - I love when the Bartenders call me "Baby" without being skeezy.
Four stars for being TOO exclusive (since you do need to have a connection to get in) and for spending all your hard-won Vegas winnings in one place...
