Humans have been burrowing under the Earth for reasons both nefarious and innocent since time immemorial. In the past, subterranean caverns and tunnels might have provided a safe haven for organized crime or shielded citizens from an anticipated nuclear holocaust. Nowadays, a number of them host rather unusual spots to drink and dine.
From a restaurant in a cave that once harbored buccaneers and guerrilla fighters, to a speakeasy in an abandoned New York subway tunnel, to a covert nightclub that once birthed a cultural uprising against the Soviet Union, these underground spaces are packed with stories. It just goes to show that you never know what might lie right beneath your feet.
