The tour includes a 15 minute film about the history of the factory and the types of cocoa beans they use. When finished, you already have an appetite for chocolate.
Next is look around the chocolate museum, which is fact the old factory that dates back to the early 1900's. It still contains various pieces of equipment and machinery.
The last part of the tour is into the factory itself, where you will walk on an airbridge above the machines and workers and can see the whole production process from the air.
