Nightlife in Islamabad does not kick in until past midnight.
Down at the marriot underground you can enjoy music, dancing and a great crowd. However unlike in other night clubs you can get thrown out of the place for no reason at all. I get this Paki block that walks to me on the dance floor and says "I can get you trown out of this place" and the next thing that comes out of my mouth is "Oh yeah! why dont you try it". All of a sudden there are two bouncers grabbing me by my arm and pulling me towards the door. Once outside I ask the doorman "what is going on?" and he goes "I dont know, why dont you just go home".
And thats the climax of the evening.
There is no night life in the most part of Pakistan, except Islamabad. And even there, everything is finish around 22hrs !
If you are a single man, you can't share spaces with families. If you are a single woman, it's difficult to find public places at night. If you are a family, you can enjoy some time, for example in the Park of Peshawar. But all the meetings, official or not, finish at the same time. Difficult to create a social life with locals when you live there for a long time.
There is no such nightlife as that of western standard. But the view of mountains at night is remarkable...... and in mountains you don't need any other activity in night except watching the mysterious glory of mountains and enjoying the quietness of mysterious nature.
Dress Code: Depends on weather.............
When there is full moon, come out of your room and stay for a some time and watch the glory of the mountains. It will be an unforgettabe experience.
