yes they are scattered around that area. Most of the customers are japs, koreans etc. Some shops have girls wearing costumes and some rooms have different themes to suit the customers.
they are high end massage parlours located at the Huay Kwang area. U go inside..there is a line up of thai ladies to choose from 2.5k to even 10k baht for 1.5 to 2 hours of enjoyment. The lady will bring u to a room. Wash you up in the bathtub filled with soapy water. Then u lie down on a bed and enjoy her teasing your body with her tongue and boobs. Then comes the main course having her riding on top of you until you are finished. Unfortunately all MP are still closed. Really miss them.
