Watch The Sting. Some of the overhead shots of Chicago as well as a few others are near identical to the chicago Sting Alley(makes sense) section of Universal Studios Florida.
Ghostbusters And The Whiz both feature the NY Public Library as a focal point in scenes. This of course made sense when Ghostbusters was an attraction and featured an entrance are where the Firehouse is(although not identical to the one in the movie, it was once very similar) Also, the nod that is still there as an homage would be the Paranormal Travel Agency window located on one of the firehouse windows.
Also to note The Seven Year Itch. Watch that and you will see a lot of street facade looks. It is a shame so much of this is forgotten now a days.
