Hello SewHistory, thanks for stopping back
I live near Philadelphia so can share a few suggestions for that area:
-Visiting Independence Hall is a great stop (http://www.visitphilly.com/history/philadelphia/independence-hall/), being where the Continental Congressmen met, and where the Declaration of Independence was signed, it is fun to go on the tour
-Carpenters’ Hall – a short walk from Independence Hall is Carpenter’s hall (http://www.visitphilly.com/history/philadelphia/carpenters-hall/), the location of the First Continental Congress. There are also a lot of other historic buildings and landmarks around these two buildings, so plenty to discover and explore
For food, there is an excellent place called the City Tavern (http://www.citytavern.com). Also within walking distance, it is a restaurant and bar that features period food, in a period setting (plates, utensils, furniture), served by staff in period clothing. The building itself is a rebuilt version of the original from 1773, that was torn down in 1854, and later rebuilt into the structure that stands today. Many Founding Fathers ate and drank at the original during the Revolution. It’s a great stop on a historic visit
I hope that helps some
-Dan
