My friend and I walked up and were told to get in a line behind a slew of men. Women were systematically escorted past us and let in, which is to be expected at a night club. A group of three Australian men were ahead of us and were told to wait. My friend and I were told the same thing. When the woman at the door knew we didn't speak Portuguese she told us to wait.
25 minutes went by and the guys from Australia and my friend and I were still in the same spot. I'd estimate 20 guys had been let in without paying or waiting in any line while we were sitting in front of the place looking like idiots. Whenever we asked what was taking so long we were told to wait a little bit longer. Finally, a woman that spoke English came out and told us we had to pay $200 reais to get in. 200!?? Are you kidding me? We laughed and walked off, along with the Australian guys. It might have helped had they told us this from the beginning. What a waste of a night sitting in line for this glorified brothel.
My advice: We've had many great nights elsewhere in Lapa, Ipanema, and Copacabana, try your luck anywhere but here and I guarantee you'll have a better time.
