Bourbon & Branch
The goal of Bourbon and Branch is to take drinkers back to the speakeasy days of the Prohibition. To get in, you have to say a password into an intercom on one of the seedier stretches of the Tenderloin. Once the door opens (don't worry, it always does), you'll be ushered into a dark and cozy bar with hidden rooms, secret exit tunnels, candle-lit bookcases, and a fine collection of rare whiskey. The fact that there was an actual speakeasy at the location in the twenties helps make Bourbon and Branch one of the best secret bars in the city.
