Willy Wonka's got nothing on Maison Cailler: Visitors to the Broc factory of Switzerland's oldest chocolate brand, in business since 1819, can enjoy a buffet-like sampling of at least a dozen of Maison Cailler's bestsellers - compellingly smooth, sensuous bars & pralines - at the end of an exploration of the factory's facilities, which include immersive multimedia shows on everything from ancient Aztec cocoa ceremonies to the introduction of chocolate in Europe by Spanish conquistadors.
