[Nice guy]

just like to share a lobang with all the Bro. It is a spa with special service. Here is the address:

天龍三溫暖
台北市大同區重慶北路一段73號9楼

it is a very old and famous Spa. You go in, they will give you a locker. Undress yourself and go in the pool area. They have hot and cold pool. dry and wet sauna. After you bathe, you get dress into their robe. Walk into the rest area. The drink is free flow but you need to pay for food.
Then there will be a mamasan will ask you if you want "干油压",that is the code for massage with sex. It will cost NT4200 with the entry fee. The entry fee is NT500 for non peak hour and NT700 for peak hour. I am not sure of the entry fee as I never pay just the entry fee, if you know what I mean.
You will be lead into a special room. You can turn down the girl if you don't like it. The girls are usually at least 30year old and above. They are still good looking and firm. They will give you a 15 massage then follow by a full service.
I would say this is the safest and sure thing in Taipei.
Enjoy.
