Attention Newtonites: now’s your chance to learn to craft cocktails without schlepping into downtown Boston. Your local American-Chilean restaurant, Comedor, will be hosting a cocktail class that will teach you both the theory and the practice of cocktail-making, using the cocktails on the Comedor. Menu. The class is from 7 to 9 PM so be sure to grab dinner there first or at Little Big Diner across the street. Tickets: $75.
