Park Street Under is a sitcom set in a fictional subterranean bar near the Park Street subway station in Boston, Massachusetts. It was produced starting in 1979 by Boston television station WCVB-TV. This was a rare example in the United States of a half-hour sitcom produced by a local station during the 1970s. Park Street Under was, at least in popular legend, an inspiration for the NBC sitcom Cheers, which was also set in a fictional Boston bar, with several similar characters.
