+1 On Monks Café, me and my buddies use to start out the when we going out in Philly for the night. If I was in a situation where I taking girl on a date that is a great choice. It's small and I guess you could say cozy with a small back dining room, they have killer beer selection on tap and most likely wine too for her if you guys drink. In never ate there but my Mom and her boyfriend go there I found out and he's into food and wine like we are into surfing.
Dalessandro's are legit, but they've been busted for using other meats besides beef. Seriously, in the late 90's they were shut down for using horse meat.
If you want to look like a tourist, go ahead order wiz (you can smear it all over your pop-out NSP or Bic LOLOLOLOLOL). But true Philly Cheesesteaks are made with American that is pre-melted and poured on. I honestly don't talk this much trash... but when it comes to cheesesteaks, people don't know what they are missing when they talk about the most popular places in Philly. Geno's, Jim's, Pat's... they all skimp on their products that they use (I swear Geno's uses Steak-Um right out of the box)... Like most things in life, you have to dig a little deeper past the mainstream flotsam to get to the good stuff. Steve's and Chink's and Tony Luke's. More expensive, a little harder to find, but more than worth it.
