Orchard Towers regrettably is dead now. The authorities in singapore decided to get religious about it and did not renew the business license for many of the businesses there. The physical building is still there but all the bars and massage joints have been chased out of there. The most famous bar, and my fav, Ipanema has now relocated to Cecil Street. They are still keeping the Ipanema name. I used to pick up hot chicas from Columbia, Viets, Mainland chinese, thai girls etc. from there and bring them back to my hotel. Unfortunately those days are gone.
Having said that pooning in singapore is one of the most expensive in the world. I would much rather poon next door in Johor Bahru. Because Singapore is now like an Asian Monte Carlo, you will find girls of all nationality there. If you just absolutely must poon in Singapore, check out Locanto Singapore Escorts ads. Some girls are freelancers and some girls belong to a stable. Take all ads with a huge grain of salt and scepticism. Never ever pay upfront. Many will ask for a deposit upfront or a booking fee or get you to buys cards for them, don't do it.
The other thing is to check the telegram groups. DO a search on Singapore escorts or call girls, or massage and you will see many groups. U can join any of the groups that interest you.
