Bahria Town is a good place to live (I am talking about the Rawalpindi/ISB part) because I lived there for the greater part of 05 years.
There are good things and there are bad things about this place that people would never tell you.
First the good:
1. Pretty clean environments and easy facilities like tennis courts (Safari Villas), even get clay courts, some grounds and lots of places for children to play. The restaurants are chic, not expensive (but then that's really subjective) and you get all the bakeries and marts.
2. The living standard is much better with no shortage of electricity. We don't get loadshedding like any other part of the city, and we barely had to suffer anytime during the whole 05 years.
3. The areas are far from congestion and traffic and day to day pollution and the higher up the mountains you go in phase 8 and 9 perhaps even, the more fresh air and scenic the views get.
The CONS
Now let me focus on the cons
1. It's downright risky to live there. Sure, Bahria provides their own security forces, but the guards are underpaid and don't really want to work. A General's Dogs were put to sleep and his house robbed in the night by some professionals. My own house was held at gunpoint and they took away many lacs from our house. Another Brigadier's house was done for in Phase III. This was basically in Phase II and III which are well estlablished areas.
So my recommendation is for anyone, who wants to move to Bahria Town, hire a full time security guard of your own pocket, who will be able to monitor everything. Give him live video feeds of the house entrance at front and back and only then, you are somewhat safe.
Otherwise, it's just your luck that's preventing you from being robbed or plundered by dacoits.
2. The second big negative is that you need at least 2 cars to stay there. 2 is even less most of the times. My brother had to go to university, I had my university, my father worked and my mother worked. We needed 4 cars, to be able to reach the city. Had to buy 3 of them, and my mom got one through office.
It's so far away from actual civilized world, you really can't live with one car here.
3. The 3rd negative is off course, not close to Saddar, and other parts of Rawalpindi. The Airport is pretty far away, and the Islamabad Lahore causeway that connects the Bahria Town Phase II to the Airport road, is the most dangerous road in the world with at least 2-3 accidents per day.
4. There are only a few schools and they are pretty expensive, so unless you are willing to shelve out lots of money to raise your children in private schools, your wallet is going to suffer a big drain.
All in all, there are some positives and some negatives in living at Bahria Town ISB/Rawalpindi.
My gut feeling is this: If you've got the cash to spill, can afford a couple of cars, and not overtly worried about saving for every single day and the future, it's a great place to live. And also if you can bear the loss of some money in tennis courts, management fees, cable etc etc which sometimes needs to be directly hauled to your house.
But if you really don't, and you belong to the middle middle class or lower middle class, where income must be saved , it would be hell to live there.
Good luck to anyone who wants to go.
And feel free to ask me any questions you want. Have a 5 year experience of living there.
and there's no real sense of community has too much of a creepy aura. Heck if I wanted some bread how far are the shops etc? 
But the work itself is incredibly impressive
