Just a quick plug for Shiatsu-Ya Massage. It was running a couple of years ago from BKK, but now reopened near Intercon Hotel.

Its not a spa, but more like clinic treatment style, the main guy has trained in Japan for 2 years. I think its great! Very intense and professional. Booking is essential.
