Last time I was in bangkok about 5-6 years ago there used to be lot of so called "cocktail lounges". They all seem to have vanished?

Can someone advise me some names and locations.

I am for the ones where the girls/hostesses/receptionists are willing to do "more" than only talk. I know sufficient Thai to help me move around so I am fine if these places are not on sukhumvit.

Thanks...
