Soft Pretzels - Introduced to the region by Pennsylvania Dutch settlers centuries ago, pretzels have long been a favorite local snack. Philly's signature variety is the soft pretzel, an everyday treat purchased from a street vendor, corner store, or from a bakery such as the Philadelphia Soft Pretzel Factory. No matter what form the pretzel takes—braided, sticks, nuggets, or even sandwich rolls—they always taste better accompanied by mustard.
