If you want to find a non-hooker, then DO NOT go to any of the mainstream foreigner night clubs. Damn places are fucking crawling with hookers, it's insane.
You go to Nana Plaza, a known red light district, and you expect it to be full of Ho's.
What you sort of don't expect is for Coffee World on Sukhumvit to be full of Ho's too. You sit there, have a coffee and some 'freelance' ho will start to work you. Go to the classier places like Q Bar and again, lots of very fit women around, don't look like Ho's but all on the game. Hotel clubs are rife - especially places like Spasso. Even in the Hard Rock, pretty much any single woman drinking @ the bar on her own is a player.
One of the 'in' places (read : shite) is Insomnia. On a recent visit when a mate came round, I saw the following.
- Young guy walking around with a bottle of Champagne and 2 glasses, trying to hook up with a chick. He eventually got a dancer to accept a glass. She knocked it back in one and then turned her back to him & carry on dancing.
- 10 mins later, this young guy was walking around with his shirt open down to the waist, I guess if the champagne didn't work, then walking around half nekkid will...
- On the way out, we spot this same young guy just ahead of us arm in arm with a tiny little thing in a skin tight black dress. He'd hooked himself a ladyboy and I doubt he even knew it.
If you really want non-ho's in qty, you need to head out to places like Thong Lo or maybe RCA. These places are predominantly Thai. Thong Lo is for the rich & famous, so you need to be well presented. RCA is full of youth and so is better for the younger guy.
To be honest though, if you are on holiday, you are better off sticking with the ho's.
