Zac Efron had anything but a quiet Sunday night in Chicago: after a late dinner, the actor stopped in for a drink by the bar at Sunda before heading over to the Underground for the club's weekly dance party. Efron held court at a table near the deejay booth – but soon moved to the dance floor, where he got down to a five-minute medley of Michael Jackson tunes spun by DJ Rock City.
