Info from Wikipedia
The Troubadour is a nightclub located in West Hollywood, California, United States, at 9081 Santa Monica Boulevard just east of Doheny Drive and the border of Beverly Hills. Inspired by a visit to the newly opened Troubadour café in London, it was opened in 1957 by Doug Weston as a coffee house on La Cienega Boulevard, then moved to its current location shortly after opening and has remained open continuously since.
