Monday, April 26 is National Pretzel Day, and Philly Pretzel Factory has a special offer for its guests on that day in celebration.

To mark the occasion, the gourmet pretzel chain will be giving away one free soft pretzel to all of its customers with no purchase necessary.

Philly Pretzel Factory has been hand-twisting its signature pretzels since 1998. Since then, it has grown to more than 150 franchise locations in 15 states. The company says that it serves more than 5.7 million pretzels per month and more than 68.6 million pretzels per year.

In addition to its original pretzels, Philly Pretzel Factory also serves items such as pretzel dogs, mini cheesesteaks, mini cheeseburgers, pepperoni melts and cinnamon pretzel twists.
