The House of Mirth would be a great name for a bar, or a theater. Or anything, really.
Come to think of it, so would The Heart of Fools.
Coincidentally there is literally the novel "The House of Mirth" by Edith Wharton - published in 1905, it's an excellent late-Victorian/Gilded-Age period novel about the slow downfall of Lily Bart, a woman who was in New York's high society, then through a series of unfortunate events and social reproaches, descended into lonely poverty. It was quite influential at the time, portraying the materialism and shallowness of the moneyed crowd.
