The women behind Booty Jamz, the Wednesday-night dance throwdown at the Riot Room (4048 Broadway, 816-442-8179), know how to get the party started. "We can read the crowd and get girls to dance," says Madeline Farrell, one-half of the BJ team. "And once you get the girls to dance, the guys will follow." These days, Farrell and her partner, Wilson Vance, run the show on the heated patio, but they'll move inside once winter hits. Yard beers for $2 and purple drinks for $3 get bodies moving, too. "We play strictly dance songs, mostly from the '90s to now," Farrell says. "Meek Mill, Big Sean and 2 Chainz are popular." The dance-off (free for the ladies, bros pay $3) starts at 10 p.m. and is 21-and-older only.
