If you are staying in an upscale hotel. If he gives you a number call without fear and you will be sent what you desire. This gets you the best Pakistan has to offer. I have tried such twice the sex itself is not that desireable but the other stuff is. They will dance for you and have dinner with you and the sex is comfortable but certainly less wild than i fancy.
Women also hang out in the lobby and are obvious to the knowing eye.
Look for them spending aimless time in the lobby and dressed in a good clothes, mainly western. Smile at them and do some hitting and they come to you or smile back and talk to them. Another popular way to get girls is to drive around Clifton, Zamzama, point, gulf, tariq road. Look for women alone or with one other girl. They smile and act friendly.
