I love a good Penn Station sandwich; I've never had a bad one! I've had a variety of their subs and they've always been great. I highly recommend their sausage, chicken teriyaki or Philly cheesesteak, all are fantastic. They have fresh-cut fries which are always great, too --not to mention they have malt vinegar which makes them even better.
This location in particular is nice. I've never seen the place busy, and it's extremely clean. Like most of their restaurants, they setup in a cafe style so you order the food then its brought out to you. This is a great place for a quick sandwich --a sandwich that is a few notches above the typical fast food joint.
