This burnt red- and caramel-brick chocolate factory, in business since 1901, is sweet. Known for its slabs of Swiss chocolate made from Alpine-rich Gruyère milk and kid-loved têtes au choco (chocolate-covered marshmallow heads), the factory can’t be visited. But its adjoining cafe and shop can, much to the joy of locals, who flock here to stock up on chocolate at factory prices and savour hot chocolate topped with whipped cream and chocolate shavings.
