Several evenings last summer we popped up to Medici and found a real-life reenactment of those cartoon moments when the main character freezes and everything falls silent. Crickets chirping, that sort of thing. After the usual grand opening frenzy abated, the party people slinked away from Phil Romano's upscale lounge. Yet somehow Romano's hard-working fix-it man, Joe Palladino, managed to revive the place. This summer, hordes of comely youngsters bumped elbows and anything else that protruded. The well-appointed lounge now ranks amongst the hippest spots in Dallas, despite offering some of the most expensive drinks. Palladino guessed that relaxing the dress code, kicking up the music and loosening the door policy would pull the mob back, and it worked.
