Comedy thrives in dark rooms with low ceilings. At Comedy Works' historic downtown location, the generally cocktail-besotted crowd is tightly packed into the venue's cozy showroom; once the lights darken, they become an anonymous mob freed from any sense of propriety. Kept satiated by tiptoeing waitstaff, otherwise reasonable people are reduced to giggling delirium by comedians drawn to what is fondly known by fans and professionals alike as one of the best clubs in the entire country. Recent headliners Hannibal Buress, Jim Norton and frequent surprise guest Dave Chappelle are only the start of the funny business at Comedy Works.
