The Best Sight in Kreis 2, Zürich

Said to be Switzerland’s largest chocolate museum, learn about the history and culture of Swiss chocolate at this interactive space. There's a 500 square meter (5,382 square foot) chocolate shop and a 9.3 meter (30 foot) tall chocolate fountain—the giant, three-ton sculpture has 1,500 liters of real chocolate flowing through it—that's a great selfie spot. A ticket, best to buy online ahead of time, is required to visit the museum, but the chocolate fountain, the Lindt shop, and the café can be visited without a ticket. Self-guided audio tours are available in a number of languages, including English, but the real gems are the guided tours and the classes.
