When a streetcar ran down Queens’ Metropolitan Avenue in the first half of the 20th century, soda fountains like Eddie’s Sweet Shop were commonplace in big cities and small towns across America. Today, this hundred-year-old corner gem on Metropolitan in the leafy, Tudor-style enclave of Forest Hills is one of the last of its kind left in the country, and it certainly shows its vintage. On summer afternoons, Eddie’s still fills up with crowds of happy Queens kids, and the diversity of the clientele reminds you that fortunately, it’s not the 1920s anymore. The shop itself, though, is practically unchanged – every piece of equipment behind the counter, from the shiny Frigidaire to the tiny metal cabinet hand-painted with the words “hot fudge,” could be from a museum.
