Philadelphia has an amazing food scene. One of our favorite spots is Indeblue an upscale Indian restaurant in the heart of downtown that has a great tasting menu with wine pairings.
Since Philadelphia is one of the oldest cities in the U.S. it is filled with historic charm. McGillin's Old Ale House is one of the oldest bars in the city with taps that have been serving ale since 1860.
Yes, be touristy and visit the Liberty Bell and Independence Hall. If the line for the Liberty Bell is too long, you can see if from the lawn if reading all the history and getting up close is not on your wish list.
