SEEN ON THE SCENE: There was a high-powered crowd spotted dining at Gene & Georgetti the other night — including Chicago Police Supt. Garry McCarthy confabbing with former Board of Trade CEO Tom Donovan and City Club of Chicago’s Jay Doherty; plus ex-Mercantile Exchange top guy Leo Melamed, Judge Michele Lowrance, Edelman PR honchos Alan VanderMolen and Dominick DiFrisco, and investment pro Joan Steel. … Taj Gibson was spied making the scene at Gibsons on Rush, while “Chicago Fire” actor Eamonn Walker was dining next door at Hugo’s Frog Bar. … “Awkward” MTV star Jessica Lu was back home over the weekend — and dined at RA Sushi in Lombard, where her brother is a chef.
