The Biltmore's grand Frank Lloyd Wright-inspired architecture is far more present in The Mystery Room's small, cool and cave-like atmosphere. The musty smell in the room reveals its history back when it was used in the Prohibition Era under the name Men's Smoking Room. The imposing grey stepped column walls surround just under 30 chairs, which do fill up quickly already as the bar is only open Sunday nights for three hours from 8 until 11 p.m.
Back when the room still functioned as a speakeasy, the stained glass ceiling functioned as more than just a decorative accent. When hotel employees spotted police cars driving up the single winding road to the resort, they would shine the spotlight on the hotel's roof into the room alerting drinkers that its time to pack up and go back to their rooms. What now is the entry door used to be an exit door only behind a wall sealed off from the rest of the hallway so that police wouldn't see guests leaving
There's one bartender standing on the opposite side of the room from the door. With seven liquors, one liqueur and some fresh fruit and juices, she does her best to accommodate drink requests. Her take on a whiskey sour is whiskey and lime juice with muddled blueberries and Luxardo cherries. There's no menu, but she knows the basics and is more than willing to experiment if you tell her your favorite spirit and the flavors you typically enjoy in a drink.
