Alcôa
This pastry shop opened in 1957 in the city of Alcobaça, and six decades later it expanded to the capital. You can now try the tarts together with “monastic pastries” that follow age-old recipes by Cistercian monks, all in this small shop on Chiado’s busiest street. Its rise to fame in Lisbon happened in 2014, when it took the top prize for best custard tart in an annual contest.
