The Crystal Ballroom first opened in 1914 and has since hosted performers ranging from ranging from Rudolf Valentino (who came to dance the tango) and early jazz musicians to James Brown, Marvin Gaye, and the Grateful Dead. The McMenamin Brothers (of local brewing fame) renovated the ballroom in 1997 and refurbished its famous “floating” dance floor, which sits on ball bearings. The venue now hosts a variety of performances and special events nearly every night of the week. Lola’s Room, a smaller version of the Ballroom, is on the second floor and also has a floating dance floor. Ringlers Pub occupies the ground floor.
