Thank you to Tony Villella for contributing this great old image depicting teens and a few Hialeah High cheerleaders at the McDonald's on West 49th Street (Palm Springs Mile) in Hialeah. You can see the open air counter where you placed and received your order and one of the several concrete tables and benches that had decorative tiles embedded in the concrete.
This McDonald's opened in the early to mid 1960's (prior to 1965 as I recall) and was one of the first McDonald's in Dade County at the time. I remember the Filet O Fish sandwiches were 25 cents and they tasted a lot better than today's Filet O Fish that they serve.
