To the left outside of Louis Italian American Restaurant, there is
a vintage poster advertising Palisades Park Amusement Park. That was a hugely popular place in the New York metro area back in the day, and was located in Cliff Side Park / Fort Lee, New Jersey. In fact it had just closed the year before the Godfather came out. So it's closing must have been in the news around the time this was filmed. I remember that place, and have photos of me there in the late 1960's. It's now the site of apartment buildings.
