Unlike most speakeasies, which lack real, honest-to-goodness Prohibition authenticity, The Mystery Room at the Arizona Biltmore has been around since the good ole days of illicit booze consumption. Originally serving as a liquor den under the guise of the name Men’s Smoking Room, The Mystery Room now (legally) serves seven liquors, one liqueur, and some fresh fruit and juices, but at a pretty penny. The password to enter changes weekly, and while it’s posted on channels as mundane as social media, you can be sure it’ll be something eerily cryptic. After undertaking the journey from the Biltmore lobby to the second floor secret corridor, you’ll be rewarded with awe-inspiring gold-leaf ceilings inlaid with glass and photo walls reserved for glamor shots of celebrities who frequented the haunt in the ‘20s. But don’t waste time knocking to get in; here, you’ve got to take the risk of opening the door yourself.
