Here is what the page at club.ru has to say about what goes on at club one more:
[quote(translated)].......Merry parties, business meetings, corporate holidays, late supper, the pleasant conducting of free time, secular life, happy idleness, supper on the reasonable price......[end quote]
I'm not sure under which of these categories you will find "wild ENF stage shows", but its probably not under "supper on the reasonable price".
Most likely "business meetings"....
