Are they just male disco places? No
Shirtless guys? Yes, some are
Good places for a farang to meet thai locals? Hmmm, depends on who you are. Looks and attitude are important. Some boys are mb, some are not. Many are there just for fun, drinking and dancing.
Are there "sleazy" corners for indecent (or decent) touching/kissing: You know DJ and G are discos, like anywhere else in the world.It is not like a boybar or gogo. So don't count on any "sleaz". But you know, when the drinks get in and it is late, I have been kissing in DJ, but nothing more...oh yes dancing.
