Childhood fantasies meet grown-up flavors at this petite Chinatown pastry outpost, where Japanese-import chef Mio Ogasawara turns out a three-course dessert menu of stunningly lovely sweets (listed on edible paper, of course). Artfully prepared and deliciously balanced, desserts this good deserve to be a meal of their own. 5040 Spring Mountain Road #3, 702-290-7181. Mon & Tue, Thu & Fri, 6 p.m.-midnight; Sat, noon-midnight; Sun, noon-9 p.m.
