The Tastykake brand is as much a Philadelphia tradition as its culinary counterparts -- the soft pretzel and cheesesteak. So it is no surprise that the company chose a Philadelphia location to open its first outlet store in the Grant Plaza II Shopping Center in the Northeast section of the city.Beginning September 20, Tasty Baking Company (NYSE: TBC), will open its first "Tastykake Thrift Outlet" to the public.
