In what is now a semi-annual tradition, Dine Out Boston returns to offer hungry diners special prix fixe menus fit for any budget. For $15–25 for lunch or $28–38 for dinner, with some establishments serving both, patrons can sample offerings from some of the best restaurants in Boston and beyond. From March 3–8 and 10–15, choose from Hub mainstays like Union Oyster House, Jasper White’s Summer Shack, Top of the Hub, Legal Sea Foods (with several locations participating) and all local outposts of Davio’s Northern Italian Steakhouse (including the Back Bay flagship, pictured), as well as hot spots both old and new in Cambridge, Brookline and the suburbs. Instagrammers can even win $100 gift cards daily by uploading their best food pics and tagging them with #dineoutboston and the eatery’s name.
