This Christmas a veritable Bavarian bonanza is taking place in The Crystal, one of the world’s most sustainable buildings. Visitors can shop at the indoor market, visit fairy lit chalets serving authentic Bavarian food and drink and watch family-friendly stand up comedy from The Official Comedy Club (1pm). There will be Christmas movies on both Saturday (Home Alone) and Sunday (Elf) at 2.30pm and an interactive winter sports arcade where visitors can try virtual snowboarding, skiing and snow globing. Visitors can turn up on the day or book in advance from Friday November 6 and pay on the door. Pre-bookers will receive a free glass of mulled wine and kids will be treated to a gingerbread heart.
