For me and my Shiloh neighbors, there's really no need to travel to the much larger and more distant Malcha Mall, because, whether by car or public transportation, it takes barely half the time to get to Pisgat Zeev. Many of my neighbors also work in Pisgat Zeev and Neve Yaakov in all sorts of jobs.
I must admit that I don't really know all of the Jerusalem neighborhoods. For me, Gilo is as foreign a place, if not moreso, than Pisgat Zeev-Neve Yaakov is for many. Yes, Jerusalem is a big city.
