Jack's Cameras in Philadelphia still exists; in fact, I still take some of my 35mm to them for developing (E-6 and C-41). Of course, none of the old locations on that receipt exist anymore. They used to be a large regional chain, but the death of printing caused them to go from about 10-15 stores across the greater Philadelphia area to 3 stores, none of which are in center city anymore. The one I go to is in the northeast (most suburban) corner of the city, about 100 yards from the city line.
