Annual Observatory Day of the Dead and Halloween Costume Party

Partake in this ghoulish Mexican holiday with traditional corpse-raising treats. Decked-out attendees—skeleton garb has been a popular choice—can chow down on the morbidly named pan de muerto (bread of the dead), decorate and eat their own sugar skulls, smash a piñata and leave an offering to the departed at Rebeca and Salvador Olguin’s Altar de Muertos installation.
