Celebrate the day when the veil between this world and the next is the thinnest with some chocolate! This Saturday Somerville's Taza Chocolate will be parading from the Union Square Farmers Market to their factory store to celebrate Dia de Los Muertos (that's Day of the Dead, gringos). Back at the factory there will be "Mass-Mex" munchies, Mexican coffee samples, "El Mariachi" mole beer by Cambridge Brewing Company, and of course chocolate. Taza will be selling specialty Day of the Dead cocoa creations including chocolate skull lollipops and special three-chili and cinnamon chocolate in their trademark hockey puck-shaped blocks. Wear a Day of the Dead costume and get diez percent off!
