The Building, on CBS
IMDb; Sitcoms Online; TV Tango; Wikipedia

A clever and witty and humorous and fast-paced show. Bonnie Hunt played a struggling actress in Chicago. It was a great ensemble show, with actors who would also work with Bonnie on other shows, including The Bonnie Hunt Show and Life With Bonnie. I dunno what else to say, except all these shows have a sort of realistic, simple, unpolished feel about them that's rather refreshing. "The Building" is probably my favorite of the shows Bonnie's exec-produced, as well as starring in. I also liked the theme song.
