This place is staple and one that I frequented when I lived in Pittsburgh. The pretzels are always fresh, delicious, and inexpensive. They have a veggie pizza (on pretzel) that is amazing and pretzel dogs. They also have a wide variety of flavors for their pretzels and dipping sauces. When I visit, this is one of the "must-go" places for me.
You can't go wrong with The Pretzel Shop/
