Known as Robert Duvall's favorite club (he talked about it during an interview with Mike Wallace on "60 Minutes," Black is a great place to go for eye candy.

As the others have said, it is highly overpriced. Some girls will not budge from their US$300 asking price, but some will. I got a young Marilyn Monroe look alike to go to my hotel for 300 pesos (US$100), but her attitude and performance sucked.

One tip: bargain in pesos, not dollars. You are in Argentina, you have no dollars. You don't even know what they are, right? Stick to pesos...
