I have a friend who lives in Bahria Lahore.
I met him over dinner recently at Namak mandi restaurant on Peco Road. He told me he drove through LDA Avenue through Jubilee Town cutting across Raiwind Road and reached Shaukat Khanum. At the moment, it seems Bahria Lahore is a bit far flung, but very soon all these areas will become heavily populated inshaAllah.
Any way, what I dont like about Bahria Pindi (it is not in Islamabad even if you like to call it Bahria Islamabad) is that you have to go through PWD main road or through the narrow streets of Gulraiz colony to reach bahria pindi - unless of course you want to drive all the way up to Rawat to enter Bahria.
Any way, inside Bahria, I notice that it does not give the open feeling that you get in DHA Phase 2 Islamabad (DHA is in Islamabad zone V while Bahria is in Pindi). DHA is more open and wide: streets and especially distance between the edge of the street and house is more in DHA and less in Bahria.
