Pastry chef Tatum Sinclair’s Pavlova could convert even the most ardent chocolate lover. At first glance it looks like a black-and-white onyx paperweight, but when you smash open its meringue shell, beautiful, colorful, unexpected things spill forth, including sesame mousse. Accenting that may be tropical fruit sorbets the color of sunshine and purple hibiscus Dippin’ Dots or market berries. It all depends on the season and Sinclair’s whims. $18. 916 W.
