I'll be in PHL a few times in the coming months, so I'll keep an eye on this thread and see if it fits any of my schedules.
I haven't seen this thread about cheesesteaks, but I visit omni board just a bit more than I fly Uzbekistan Airways.
I think the best place in Philly for cheesesteakes is Lee's Hogie House (or similar name, definitiely Lee's). It's in Wynnewood, conveniently close to those who live in that neck of the woods (JayBrian).
It's right next to the Wynnewood Theater (IIRC) which recently closed (IIRC!!), and next to a toy store. My memory is fading me, but Lancaster Avenue comes to mind.
