From where you are, I would suggest going to Holt's downtown. You can do other site seeing in the city and it's very close to Rittenhouse Square that has some good shops and restaurants. The Reading Terminal Market also has some great places to eat but that is over closer to Independence Hall, the Liberty Bell and the Constitution Center. Definitely worth a stop if you're over there.
Just so you're aware, NJ has a 30% cigar tax while PA is, for the moment, still no tax on cigars. So crossing the bridge for your cigars also makes monetary sense.
As for meeting up, center city is about a 45 minute drive for me, so unfortunately I couldn't really "play it be ear". If you know when you plan to be there, I can try and make it happen, but otherwise, enjoy the city!!
Go Eagles!!!
