A throwback to Prohibition-era San Francisco, this veritable speakeasy asks visitors to stick to a series of house rules--no cell phones, no standing at the bar, no photography--as a condition to enjoying their highly regarded cocktail creations. Their liquor selection include rare delights such as Glenmorangie Margaux Finish Scotch, import-only Tapatio XA tequila, and Crown XR Canadian whiskey. Buzz without a reservation at the innocuous unmarked door, supply the password “books” and you’ll be shuffled into a beautiful 1920s library where expert mixologists will concoct something delicious based on just a few hints on your part. Don’t miss their signature ‘Cucumber Gimlet’ with cucumber-infused vodka, lime juice, elderflower syrup, orange bitters, and champagne; or their peppy “Rouge No. 10” with black pepper-infused gin, muddled strawberries, lime and pastis. Reservations are required for dinner.
