Tucked into a storefront on Prince Street, year-old Sage is the kind of restaurant we love to honor. Why? Because it shines on the short list of quality restaurants in the North End. Because it only has 28 seats, guaranteeing individual attention to every diner. Because the handmade gnocchi could float on a feather. Because the waitstaff is amiable and efficient. Because the wine list is small, reasonably priced, and ideally suited to the cuisine. Because chef Anthony Susi went out, saw the world, came back to his home (he’s a North End native), and brought the restaurant that he cut his teeth on. Get the picture?
