It depends on what type you’re referring to.
RCA (Royal City Avenue) has a string of regular night club and discos.

There’s also a few night clubs around the backpacker’s haven, Khao San road.
If you’re looking for the night clubs and discos that are basically brothels, then there’s Soi Cowboy, Soi Nana, and Pat Pong.
