Panama St isnt a street that you would know of unless you were a photographer looking for a picturesque, cobblestone street in the Rittenhouse neighborhood.  It has that old school Philly look to it with some beautifully cozy rowhomes lining a cobblestone street that isn't driven on unless you live on the block and need to unload your car.  Its the 2400 block of Panama St which is located between Delancy and Pine.  I use this location a lot for couples looking to do photos at Rittenhouse Square and the South Street Bridge because its right along the walk in between the two.
