The New York State Amphitheatre (aka Billy Rose's Aquacade) survived 2 Fairs, only to be demolished in 1995. Though preservationists lost the battle to save the Aquacade, a few relics were salvaged and incorporated into the sad, sorry little snack bar that now squats on its former site.
I believe these gates are original from the Acquacade.
I have never seen this snack bar open for business!
