[1]  [DOC] Opened in 1953 or 1954, and one of the original "folk cafés" of the 1950s/1960s, Bunjies Coffee House & Folk Cellar was situated at 27 Litchfield Street (just off Charing Cross Road), London WC2. Below the café, in a 400-year-old wine cellar, was an influential music venue which changed little until its closure (and conversion of the premises into a restaurant) in 1999. Allegedly named after the first owner's pet hamster, the venue featured, early in their careers, Tom Paxton, John Renbourn, Bert Jansch, Bob Dylan and Paul Simon. Al Stewart secured a residency at the Folk Cellar in 1965, at the age of 19, which was a significant factor in his later success. [END]
