Since March, Rory Macdonald has been baking cranberry-and-walnut bread, gianduja kouign amann, and sandwiches at his Flatiron shop Patisserie Chanson. It's a higher-end pastry shop, for sure, but one you can still regularly stop by for a breakfast pastry, a quick lunch, or (in a nod to Macdonald's London roots) afternoon tea.
