La Mallorquina ★ 4.5
La Mallorquina on Puerta del Sol in Madrid has sold the napolitana de crema (custard-filled puff pastry) since 1894. The 19th-century counter still queues out the door every morning.
Tip: Walk-in only; the counter fills up by 09:30. Cash strongly preferred at the counter. The upstairs cafe takes seated customers.
