The Thai Bistro Club Nightlife.
Just for comparison this is Aldjunied in Singapore a typical red light district with plenty of freelancer around. Actually there is nothing to say against it this is all totally legal according to Singapore law.
Girls working in the night
Since the young women sitting here stepped out from cars with Malaysian license plate in the late afternoon it makes sense to assume they are from Malaysia.
The Kuala Lumpur nightspots where something is going on.
A good alternative could be just have a look around in the hotel nightclub maybe after 11 pm young local women are around who usually are positive do meet guys but keep in mind most are around for business have a look Malaysian girls in the night-
shift have a positive attitude
This are the main nightlife tourist spots in KL most oriented to dinner and beer bars definately no girls pick up. The whole athmosphere in the night is not like it is in Thailand or Cambodia and Myanmar in Malaysia it is business only very rarely it turns into somehow romance. So if you want to have a good night in KL with some add-on never forget to take some money with you the more the better. To make things easier ATMs are set up everywhere at the important points which allow a quick access to cash and take high commissions for it.
In the Thai Bistro Club the ladies are much less aggressive. If you need money for any reason there are several ATMs that are about 3 minutes away. Jalan P Ramlee is named after a famous Malaysian artist and a monorail station is just a 10-minute walk away.
Do not think too much about safety, even at midnight the area is absolutely safe although there are some ladyboys at the monorail intersection
