Plus ca change, la meme chose
The discussion on which club is best has been going since the clubs started. Picking up on some points colleagues made, I would just add that, as a generality, over the years, Oase has always been a bit livelier and with more well presented girls than World which has always tended to be a bit more relaxed and with more natural girls, so the difference currently noted is not anything radically new. As for Oase not doing so well now, clubs always have ups and downs so I don't read anything into this.
World is at the moment unfashionable on this forum, but I read elsewhere of very satisfied customers and excellent service.
As for Sharks, well, it has its supporters and detractors. It is currently the go-to club for foreign visitors and I suspect may soon pass its peak. Several members have made points about quality vs quantity. Especially with the attempts to introduce restricted service levels
As PL (I think) always says, what really counts is finding the girls who really deliver, and that can happen in any club any time, or not, as the case may be.
Best option: try two clubs in one day
