So I guess the current i.e. tentative idea that seems the best for now is: (NOT CONFIRM)
Afridi-Inn (Do Darya i.e. Phase 8) - Gathering + Iftar/Dinner 
Ample parking space in the locality with several empty lanes, plus huge area to meet greet and easy on the pocket food items.
HB would get a discount as well so I feel its a Win-Win situation. 
Area opposite to Charcoal or next to HotBite can serve as a gathering place.

Note: Can't cater to individual choices since a decision has to be reached keeping in mind all members. Yes it is NOT a central location but somehow it is affordable, weather would be pleasant in this region and has a good location for everyone to be together.
