One of San Francisco’s most delightful shopping complexes takes on a seasonal glow when it illuminates for the holidays. Ghirardelli Square, the historic former chocolate manufactory, turns the lights on its 50-foot Christmas tree with the 36th annual ceremony in the plaza. This year’s family-oriented event features appearances by the ever-popular Harry Potter, as well as Snow White from the local production of ‘Beach Blanket Babylon’. The festival also includes live performances by local children’s caroling groups. Even Santa and Mrs Claus are expected to attend.
