Any discotheque for non smokers ? (Santiago de Chile)

Sometimes my friends invites me for night out in some discotheque o club for dancing or eating etc. So far i have been to some places where there is no ventilation and still people smoke a lot and each time i was back home with burning eyes and cigarettes smell all over my body and clothes
Is there anyplace within Santiago without this, with drinkers and non vegetarians is easy to manage but smoking is something really serious.
Anyone knows any place ?
Thanks in advance
