Share 'Who has the highest concentration of Chocolate shops?'

This is just for fun but does anyone know what city in the world has the most chocolate shops per capita? Im thinking probably Paris, London, or NYC, but maybe not- does anyone know for sure? Choc shops meaning only those where bar and bon bon/ truffle type chocolate is the #1 product: "Chocolateries" (not patisseries, grocerys, or bakeries).
