With the popularity of ABC's Dancing with the Stars, you'd think old-school ballrooms would be packed nightly. Sadly, Phoenicians seem to prefer watching the foxtrot on television, rather than trotting their asses out to actually do it. The exception is dance instructor Chad Lakridis' Ballroom Bash night, a monthly social gathering with music, food, door prizes, and dancing from the Argentinean tango to the West Coast Swing. Lakridis is no Emmitt Smith or Mario Lopez, but his winning smile and rugged 5 o'clock shadow combine for a mug that's easy on the eyes a saving grace for the ladies because those lacking a partner can always team up with the instructor. A half-hour lesson precedes the dance portion, with Lakridis cheerfully offering newbies tips on how to negotiate the often-crowded, 4,200-square-foot dance floor without getting trampled.
