Hans Koch makes leather handbags. And belts. They're original and beautiful and come in a remarkable variety of color combinations and textures and he sells them in a small store on Prince Street in Soho. The store is remarkable not only for the product, which is charming and well made, but for existing at all in Soho which has become like one vast mall of familiar, cookie cutter stores selling products available at any mall in the country. And here's the kicker: if you get on his mailing list, either by buying something or just asking, he'll personally call when he's having a sale to let you know. Can you beat that in this impersonal city?
