Nice place I like to go for a massage when in Bangkok is Akane in Chitlom. The place is supposed to do a Japanese massage(not that I could tell the difference). I have always received good service here and a good massage although it is not cheap and full service is not on offer. You can basically get scrubbed with salt, washed down, massaged by 1 or 2 ladies and have a happy ending or blowjob. The place is right by the Chitlom MRT station, they also have another place in Soi 33 off Sukhumvit(never been to that one). The one in Chitlom is the bigger of the two. They give you a complimentary drink as well. All the times I have been there I have gone for the 1780 baht version and can recommend it.
