I stopped in this privado on Friday at about 5. When I got to the door there was an Argentine waiting outside. After about 3-4 minutes the mamasan let him in. I continued waiting. After about 5 minutes the line started to back up. Four other guys (Argentines) came and were waiting in line behind me. Soon I was let in and was told that I could not have a 1/2 hour session. It was either an hour session or nothing. I left.
I have always liked this place and will probably use again but the previous report that it is busy in the afternoon is so true.
