Summer in the Fenway is about more than Game Day these days. Of course, the 2018 World Series champs' ballpark is the neighborhood’s heart and nothing beats watching a game at Fenway Park: It’s pure Americana.But this much-changed, much-expanded area is sizzling with restaurants, arts and entertainment, too. Really, there’s so much to do in Boston’s western reach there’s no need to set foot in the Fenway’s more visited neighbor, Back Bay.
