Since its 2009 opening, The Blue Ox, an upscale, casual American restaurant in Lynn, has been celebrated in its neighborhood and surrounding area. The Blue Ox has garnered awards and accolades for its signature Sin Burger, winning Boston Magazine’s “Battle of the Burger” competition three years in a row and was a critically acclaimed entrant in the South Beach Food & Wine Festival. The concept of affordable, destination dining just around the corner was a huge success.
