Whether you get ‘em fresh from a South Broad Street sidewalk vendor or in a posh Walnut Street deli, a famous Philly soft pretzel is always a salty, tasty treat, especially when topped with mustard.

Pretzel historians say the earliest were pretiolas in 7th Century Rome, then bretzels in 15th Century Germany. They sailed to America in the 18th Century with Pennyslvania Dutch settlers, and are now enjoyed in Philly since the 19th Century.
