It is highly likely that All American in Massapequa has had a line every second since it opened in 1963. To this day, its simple hamburgers -- bigger than White Castle, smaller than McDonald’s -- come in at less than a buck-50, which makes it completely cost effective and a fairly sound investment to consume a dozen. In true old-school fashion, you order at a long counter and eat your food wherever there’s space -- the scattered outdoor tables, a counter on the front wall, or perhaps sitting on your tailgate. No matter how highbrow the scene turns, the true food soul of Long Island lies in a few cheeseburgers, a square knish, and a chocolate milkshake.
