New cheesesteak restaurants come and go all the time, but two of the oldest—Pat's and Geno's, at the corner of 9th and Passyunk—have a longstanding feud worth weighing in on. It comes down to a matter of taste. Both serve equally generous portions of rib-eye steak, grilled onions, and melted Provolone, American, or Cheese Whiz on freshly baked Italian rolls. The main differences as far as we can tell: Pat's claims to have invented the cheesesteak; Pat's meat is chopped;
and Pat's exterior is more, ahem, understated than Geno's neon extravaganza.
