[DUCKIE]

Maybe it's just me, but for a nice chicken cheesesteak and regular cheesesteaks, I recommend a little place right next to the Franklin Institute on the corner of N21st and Race St. (Visible from F.I. parking garage entrance) I don't remember the name of the place, but every time I go up to the Franklin Institute that is where we stop.
PS-They like you to order before getting a table when the place is hopping (which it has been every time I go) so I just get it to go most of the time.

If you go down to Old City to see the liberty bell (no ticket needed), or Independence Hall (free tickets available at visitors center -but you might not need them in March-), there is a buffet inside the Bourse bldg. opposite the Liberty Bell Center. Pick what you want and pay by the pound. Not a ton of seating though.
