The Soapy massage at Pattaya is good, hooked up with some hotties when I was there a couple of years ago. I think its called Honey2 and something just up the road. if you want something really trashy where all the old white guys hang out, go to Soi 7.

I thought Japan was shit, expensive and hard to find. nothing beats Thailand.

If you are only in Bangkok and Pattaya for one night, I suggest a soapy massage for a sure bet, otherwise you have to spend time talking up the girls in the gogo bar and arrange to go back to hotel.
