In keeping with their annual tradition, Masa in the South End celebrates Halloween in grand style with a weeklong Dia de los Muertos party. That means you can sip signature Masa-ritas for $5 apiece all week long. Once Saturday and Sunday roll around, the festivities are in full swing with costume contests, tapas specials and DJ Ricardo spinning tunes into the wee hours. Call 617.338.8884 to book a table or just swing by for a casual bite and cocktails in the bar.
