White Mana Diner shared by @eater says: ""The term smash burger may have been popularized in 2007 by Denver’s Smashburger chain, but the concept has been around far longer, dating back nearly a century ago when burgers were thin, cooked to a well-done temperature, and flattened with a spatula during the cooking process. White Mana started life as a kiosk at the 1939 World’s Fair in Flushing Meadows and was later transplanted to a nest of highways at the foot of Jersey City Heights. The burgers are ultra-thin and taste as if they’ve bathed in the grease of the millions of patties that came before them."" on Postcard
