Ah-ha! The closest to the real thing you'll get in the valley.
I walked to the counter and said 'Wiz-With' and that is what they served me, no questions asked!! If you know philly's then you undoubtedly know that is how to get it.
They have a picture of Genos, Pats, and Jims (og) on the wall where you walk in...so they set their expectations high as soon as you see that.
I have to bash on some of the reviews I have read asking for Peppers or other crap on the roll. You guys are a disgrace to rolls and if I heard you ask for that in person I'd hit you with snowballs.
This place is awesome. Go there and get a roll and you won't regret it!
