I generally prefer to avoid chain and fast-food restaurants, but I'll definitely be back to this place. I visited the Manchester Rd. location, but I imagine they are similar.
The food was very good... as a vegetarian, I'm tired of the usual tuna or veggie options for subs, but Penn Station offers an artichoke sandwich that was very tasty. It came with mushrooms and mayonnaise too. And the best part is the fries they make - normally I don't associate subs with fries, but they make it work.
The service was a bit slow - it took a while from the time we ordered at the counter until the time they brought out the food. It especially felt slow when compared to a place like Subway, where they make everything right in front of you. But what they lack in time efficiency, they make up for in fresh ingredients.
This place is a good deal and tasty for everyone!
