Owner Alfredo Giannaccari’s started his restaurant journey with a Tuscan dining room in Newtown Square, where affluent clientele nibbled on imported cured-meat plates. Mercato is a shining example of what Giannaccari and his wife, Barbara, have done best at previous restaurants. Not surprisingly, the passionate Giannaccari—a native of Naples, Italy—is the driving force behind Mercato. His knowledge of meat aging and sausage making (procured from his father’s butcher shop), bread baking (from his uncle’s bakery), and hand-pulled mozzarella is executed here with the utmost grace and skill. He’s not trying to complicate things. He’s simply focusing on doing it all well—and with authentic, high-quality ingredients.
