Where: Bambuddha Lounge at the corner of Eddy and Larkin in the Phoenix Hotel.
How: With libations from a cash bar, including the "Unknown City Cocktail." The ingredients are a secret, but the effect will be all too apparent.

How Barnes & Noble editors describe the book:
"Arsenal Pulp's Unknown City books take you to places where Fodor's editors dare not go. With its offbeat, often scandalous history, San Francisco seems a prime candidate for the series. San Francisco: The Unknown City doesn't disappoint. Insiders Helene Goupil and Josh Krist escort readers on tours of the city's hidden nooks and dark crannies. Gangland massacres, multilevel sex clubs, even active opium dens and (blush) private karaoke rooms! Along the way, the good-natured coauthors offer tips on secret dining pleasures and bargain shopping secrets."
