Two of us are visiting Philadelphia for the first time, staying in Center City. We've been to a few times already and really like the Reading Terminal.
Is there a restaurant / pub / place selling food that we shouldn't leave town without visiting?
We are open to everything except a multi-course fixed tasting menu. A la carte small plates are fine though.
If the can't miss restaurant is outside of the center city area, I'd like to know about it as well.
Thanks for your help.
