Let them eat cake — for breakfast. Sure, the French call it pastry, but Katherine's takes the yen for cake seriously, as evidenced by the crowds that gather here early in the day, enjoying huge almond croissants dusted with powdered sugar and big spiky things made of meringue, as well as coffee and even real meals — quiche and omelets and sandwiches and salads. Katherine's stays open through mid-afternoon, but the bakery case is at its best early in the day.
