Trick or treat? From 6 to 9 p.m., you can do a little of both at Mascherata Veneziana, a fanciful Italian masquerade hosted by the Kitchen Cabinet and Rialto
restaurant (Charles Hotel, One Bennett Street, Cambridge,
617.661.5050). This evening of cocktails, Italian dishes from Rialto
chef Jody Adams, and masked revelers benefits the Greater Boston Food
Bank, so start Halloween a day early and put on a whimsical mask to
provide 155 meals to those in need. Tickets ($85) are available at www.gbfb.org/kitchencabinet.
