37 is a brothel ... no bar there !!!
you sit on a worn out sofa in a grotty reception area and wait for the girls to come.
If in HK you need to take your guests to a real night club ... like BBoss where you spend about $4-5K
(each person) for the time in the club and taking the girl out to a motel to nail them
can I ask what language your friends speak ? ... and why it would be complicated ?
