One word: appeltaart. That pretty much sums up the appeal of this popular little café with traditional wood-beamed ceilings. Here, locals, students, and tourists-in-the-know gather for slices of this thick, cake-like Dutch specialty, studded with fresh apples and cinnamon, topped with housemade whipped cream if you'd like, and best washed down with a mug of steaming fresh mint tea. This slice of Netherlandish heaven can be savored on Winkel's large patio—on the edge of busy Westerstraat and continuing across the street into the Noordermarkt—which is especially tempting on sunny days and almost impossible on Saturdays before 5 pm, when crowds spill over from the busy outdoor organic market. Otherwise, wait for a seat and enjoy a tasty sandwich, salad, or pasta dish if you're hungry for more than just sweets.
