Patpong is famous as a tourist market selling both real and fake designer goods, DVD's and lots of souvenirs.

However, it's more famous as Bangkok's first red light district. Inside the clubs downstairs the bikini- or even naked ladies dance on stage, upstairs feature famous and oh so original shows like the banana show (guess what goes where), women smoking cigarettes from all openings etc. If you have never seen something like this, this is the place go. Most bars have touts outside trying to get you into their bars or see their sex shows. It gets a mixed tourist audience, so it's not too seedy, although everyone complains about rip-offs. location

In the same area you can find gay bars and discos in Soi 4, male go-go dancers at Boys Town, Surawong Road, and Japanese hostess bars in Thanya Road.
