Club Do-San
From Tardis Wiki, the free Doctor Who reference
The Club Do-San was a nightclub in Shanghai owned by Woo in 1937. Kwok met Vogler at the club, and discussed their arms deal at the Gongpinglu Wharf later that night.
After he helped the Fourth Doctor and Romana I defeat Hsien-Ko, Woo planned to close the club down and open a new club in San Francisco or Los Angeles. (PROSE: The Shadow of Weng-Chiang)
