Any food complaints are small compared with the service issues Blue Pear faces. Set into a former general store (circa 1754) that Barnes spent $1.4 million to renovate, the bistro was always meant to be a more casual destination with a neighborhood feel. But its young staff has none of the polish of the Dilworthtown's veterans next door. Advice on the small wine-by-the-glass list was spotty ("I'm not very good at that," our first waitress said, blushing.) Plates occasionally were dropped awkwardly before the wrong diner and left to teeter atop errant silverware.
