Go southeast into adjacent Bucks County. Plenty of covered bridges, old farmhouses and the Delaware River. Doylestown is about thirty miles south and there is the Mercer Museum, which is filled with artifacts from the late 19th century. Across the street is the old Bucks County Prison which was converted to the James Mitchener Art Museum. There is also the Moravian Tile Works. A bit further south is Washingtons' Crossing and the Revolutionary War Museum. Around forty miles northwest is Stroudsberg home to Steam Town, which is one of the largest collections of steam locomotives and rail equipment on the east coast.
And, welcome to the forum!!
Also, check out the Allentown visitors page. They have converted some of the old steel mills to make them more visitor friendly. Can't help you with dining, it's been eight years since I've been back to visit.
