Be warned!
Reminds me when I was in London with my cousin in the mid 90's.
Chatted to two 'girls' in a bar near Soho Square, they said they knew a good club where we all could go and have a good time. Led us into a warren of side streets and then up a flight of stairs where we were met by two burly geezers who demanded a tenner each entry fee, paid the forty notes and then we were led across some kind of bridge and into a dingy smoked filled room. The tarts had disappeared by now, probably to pick up more mugs.
Ordered drinks, only champagne and came with a girl at £200 a time, they ordered more champagne. We decided to leave, had to hand over fifty notes each to leave with our looks intact.
Be warned.
