First time poster, so I hope I'm doing this right. I learned about Al's over the summer when the Post mentioned it in Style? Food? Source? It's definitely not high gourmet, but I've never been disappointed by a sandwich there.
I'm not from Philadelphia, but I've visited enough times to know a good cheese steak when I find one and this one's the best I've found. I haven't tried mushrooms because I always go for the basic, but I'm usually reluctant to order them on any sandwich unless I can tell that they're fresh, preferably wild, ones. Anyway, I was glad to see a cute article about a little guy who's doing it well.
