Penn Station East Coast Subs, a fast-casual restaurant known for its grilled, made-to-order sub sandwiches, is celebrating National Cookie Day on December 4 by giving customers a complimentary chocolate chunk cookie bite with any sandwich purchase.

“Our chocolate chunk cookies are one of our signature menu items,” says Craig Dunaway, president of Penn Station. “Baked fresh in the restaurants daily, they are almost irresistible. We thought National Cookie Day would be the perfect time to treat our customers to a taste of one of our best menu items.”

Cincinnati-based Penn Station East Coast Subs features grilled sub sandwiches—including the chain’s renowned Philadelphia cheesesteak sandwich—and cold deli sandwiches made to order with high-quality ingredients on hearth-baked bread. The menu also includes fresh-cut fries, hand-squeezed lemonade and chocolate chunk cookies baked daily in the restaurant. Penn Station offers eat-in dining, carry out and catering.
