Went to BKK last week. There were quite a few massage shops on the Soi my hotel was at in Sukhumvit area. Approached one of massage girls on the street one night and took 90 mins aroma massage. The girl said she was from Isan and she was of petite build with nice boobs and ass. The place had few levels and each room had showers. Massage was average and when not long after flipping over, special was offered. Initially offered HJ and managed to get it at 700 baht, after that offered to take off top at 1000 baht and B2B at 1500 baht.
Special was enjoyable
Not sure if I was overcharged though.
