I made a similar post on the DC forums as we are going to be there for 5 days/nights.
Me and my cousin are doing a trip to Philly in about a week (first time over to the eastcoast) and staying for 2 days/nights, we are looking for a variety of food from cheap lunch spots to a fancy dinner so please suggest away. We are also looking for possible interesting bars/nightlife places to check out a well.
Some of the places we were thinking about checking out (additional feedback on these locations would be helpful as well):
Pat's/Geno's (looking for other cheesesteak suggestions)
The Franklin Mortgage & Investment Co
John's Roast Pork
