Penn Station is a chain of restaurants specializing in what it calls "East Coast subs."

[2] The concept for an East Coast sub restaurant came to Jeff Osterfeld soon after he graduated from Miami University in Oxford, Ohio.

He began selling a version of the cheesesteak sandwich at his own restaurant, and it instantly became a huge hit.

However, this first restaurant also offered fresh-cut french fries and freshly squeezed lemonade, two items that would become trademarks for Penn Station in the future.

He began selling franchises that year and restaurants soon opened in St. Louis, Louisville, and Nashville.
