I went to the new building of Banana. It is really easy to find and a very short walk form the BTS Asok or MRT Sukhumvit.
Downstairs they do traditional Thai or foot massage (thats new) and have several relax chairs available.
Upstairs is for the massages they had in the old building, but the big difference is that it looks very new, clean and beautiful as you can see on the photos. There were about 15 therapist you could choose from, all different kinds, so many to choose from.
The owner makes you feel comfortable and gives you good and honest advise.
I'd tried some other massage places, but i am still coming back, because i think this is the best and also because the owner really cares about his business.
