Nearest Underground Station: Tottenham Court Road. Walking down Charing Cross Road from the tube, turn left into Denmark Street. Walk almost to the end, trying not to get distracted by all the guitar shops, and turn left into Denmark Place. A tiny alleyway. You'll find the 12 Bar Club on the left. You can also tube it to Leicester Square, catch a bus to Charing Cross Road or thereabouts, or wander down from Oxford Street.
