Now, let me be perfectly clear: I haven't actually sampled the wares at Phat Philly. Yet. Unfortunately I, like so many of you, have been gripped by the post-holiday need to eat only leafy greens and garbanzo beans. However, when I recover from this brief stint of healthfulness, I plan to march right over to Phat Philly for a cheesesteak ($6-$10), because it seems like they're doing it all right. Amoroso rolls imported from Philadelphia, natural antibiotic-free beef from Niman Ranch and Creekstone Farms, and, in addition to the de rigeur cheese Whiz, they also have housemade cheddar-beer sauce.
