This Park Hill space was formerly home to the Elm, a great Boston bar. It’s been other concepts since then, but nothing has stuck — which we hope changes with the W. The place is a passion project for husband-and-wife team (and longtime Park Hill residents) Ernest and Carrie Wigglesworth, who brightened up the place but paid homage to the building’s past, using milk glass from the old pharmacy that once operated here to create the bar. Burgers are the focus of the food menu, while imbibers can choose from house cocktails or the impressive wine and beer lists.
