Dear Brothers,
I have worked in Bangkok for 3.5 years. Don't go Soi Cowboy, Patpone or Soi Nana that kind of Go Go Bar. Those are the places for Western people. I always worry about the hygine there. Also, if you have chance to walk around those places around 5.00pm, you will see those Go Go Girls just come back and preparing make up. You will see their real look and for sure your little brother will drop down at once. Their faces just look like some creatures you saw in Star Wars.
Posideon, Emmanurel, Victoria Secrets, these kinds of massage places are much better choices. Sometimes, the keeper inside these big massage place can speak Cantonese. You can ask for Model and part time girls there. For models, normally cost Baht 3000 up for 1Q, part time is aroung baht 2500 for 1Q. Of course, body massage is included. Posidon has some VIP room with romantic decoration. Some massage place has special chair for different positions. Check them out.
