There is no such thing as a plain cheesecake at Kimberly Davis Cuthbert’s adorably green-and-violet bakery. There is heady amaretto cheesecake. There is sweet-tart lemon blueberry cheesecake. There are apple--cinnamon, raspberry mango, pumpkin spice, and cappuccino/white chocolate cheesecakes (45 kinds in all). But sorry, the closest this shop comes to plain is vanilla—and vanilla usually involves a cherry center and dark chocolate shavings. No plain, only fancy, which is fine with devoted customers—Renee Chenault-Fattah and Chaka Fattah and Senator Vincent Hughes and Sheryl Lee Ralph ordered their wedding cakes here.
