If you go to Bangkok make sure you visit Nana Entertainment Plaza, it is just a huge complex of bars where every girl is selling herself. The other thing you should check out is Eden Club, I believe it's on Soi 7 and Sukhumvit but any taxi driver can take you... I wouldn't indulge for fear of getting sick with AIDS, but it's something every man should see once in his life. Also Pattaya has some ridiculous things happening there.
