yum. i'm not from philly and don't know what constitutes 'authentic' there but these are somegreatsandwiches. sorry i waited months to try the place out. worst you can say about them is that there's some labor and time involved in making the sandwich fresh to your specs. call your order in if you're impatient. lots of meat, and not a drippy greasy mess like the standard cheesesteak you get anywhere else around here. your choice of cheeses and garnishes make for individually-tailored deliciousness. bay fries are good too.
