While most closed-down restaurants might be remodeled, this defunct Burger King remained frozen in time, untouched, unseen, and hidden behind a wall for years. In 1987, Burger King opened a location in the Concord Mall in the Brandywine Hundred area of Wilmington, Delaware, decking it out in late 1980s restaurant design with turquoise tables, mauve booth cushions, and blond wood everywhere.
