Wahlburgers, the burger joint being opened at the Hingham Shipyard by brothers Paul, Mark, and Donnie Wahlberg, will have its grand opening Oct. 24. The restaurant, announced just a few months ago, is being fast-tracked. It will be adjacent to Alma Nove, the Italian and Mediterranean restaurant also owned by the brothers Wahlberg (and family friend Ed St. Croix). The new place will seat 120 and serve burgers, fries, hot dogs, and shakes. The opening will be invite-only and raise money for charity. (We hear the three brothers will hit the red carpet at the bash.) The restaurant will be open for business to the public the next day.
