Davio’s Northern Italian Steakhouse, a Boston-born favorite that has expanded from coast to coast, has come full circle as it prepares to open its newest location right here in the Hub. The latest outpost—scheduled to host a VIP reception on November 23 and regular dinner service beginning November 25—is a grand, 15,000-square-foot eatery at 50 Liberty Tower on Fan Pier in the red-hot Seaport neighborhood that offers sweeping views of Boston Harbor along with Davio’s usual array of expertly prepared and elegantly presented steak, seafood and Italian dishes.
