Really drinking happens in Pakistan you just need to know where to go and it happens openly in certain restaurants. Of course there are concerts and big parties but the do not get advertised in mainstream media.
You know you should see what some people wear and you think god am i really in Pakistan. Youwon't see things in the open but it is there if you look hard enough. Yep there are plenty of shows like they do in Dubai but on the basis of invitation only.
