Gotham Comedy Club, a popular comedy venue in the Chelsea neighborhood of Manhattan, is the setting of an hourlong series that is shot in front of an audience at the club. Each episode features routines by several comics -- a list that has included such names as David Alan Grier, Gilbert Gottfried and Artie Lange -- in what the network says is an unedited and uncensored format. In addition to the big names of the field who take the Gotham stage, the show also features up-and-comers who want to make a name for themselves in the stand-up comedy business.
