Trentini’s Restaurant has been quietly serving decent Italian fare at its storefront in the Roebling Market ever since its founding in 2002. Trentini’s looks like a standard pizza joint (and the pizza’s OK). But walk past the pizza parlor into the back room, and you find yourself in a quiet, immaculately clean, and intimate dining room with waitress service. With most of the old-line Chambersburg restaurants gone, it’s one of the few options for good Italian within the city limits. And it’s a real bargain.
