If you can get yourself a wee bit out of the neighborhood, go to One GIrl Cookies in Carroll Gardens. They have a lovely dessert menu, complete with wine pairings, and a tasting plate of the day's specials that is always a treat. The space tough limited is very snazzy in a cool modernist way. They may only serve on Friday and Saturday nights.
