Penn Station isn't bad but not exactly a place I would try again. The subs were decent, probably better than subway but nowhere near as good as quizno's. Quizno's simply uses better ingredients, has subs that seemed to be crafted by a chef, so all of the flavors compliment each other while Penn Stations subs seem more haphazardly thrown together and then toasted.
Their fries are fresh, blanched first and then finished the second time in oil and as another reviewer put are greasy but good. Overall their food is adequate, with a slightly higher prices like Quizno's but without the high quality and taste of a Quizno's.
