All good things must come to pass, and Stephen Starr’s Stella is no exception to this adage. Sadly the pizzeria will host the last of its Meatball Tuesdays tonight. The popular $15 deal launched in early December during citywide outbreak of meatball madness, offered diners the choice of a romaine salad or minestrone and one of four meatball selections ranging from traditional beef, pork and veal to chicken balls stuffed with fontina. In place of Meatball Tuesdays, Stella will start offering a Monday Date Night promotion geared toward college students starting next week. It offers appetizers, pizza and dessert for $29. Diners wil be required to present a valid college ID.
