Johnny Mango's in Cleveland is haunted by several spirits. One in particular is a woman named Margaret who died when the trolley car she was riding in plummeted into the Cuyahoga River, in 1895. But Margaret is merely the oldest of at least three hostile spirits who plague the restaurant, each of whom died violently nearby. The management even brought a psychic in to attempt a "cleansing," but it didn't succeed.
