Judd Kennedy, owner of Renaissance Niteclub, announced last week that he was switching gears at his 9-year-old downtown Lafayette nightclub. Citing a decrease in revenues on nights with both DJs and live local bands, Kennedy indicates that he's changed not only the name of the club but also the crowd it targets. Sadie's Downtown seeks to cater to the "working class woman," aged 25 and older, and to focus less on its traditionally younger college crowd.
