Downtown's IDL Ballroom, owned and operated by Tom and Angie Green, who founded Tulsa's DFest Conference and Music Festival, celebrates its grand opening tonight. Look for the largest copper bar in town, two VIP areas, a vintage arcade room, a 10-by-10-foot video screen and yummy snacks from Alter [Egos] Couture Cupcakes (love these!). Until 1:30pm.
