The birthplace of Lisbon’s legendary custard tart - Pastel de Nata. You’ll find endless queues, long waits and a busy, buzzy space. Many locals think you get better Pastel de Nata in smaller establishments but this is a legendary , historical establishment. Go early to try and beat the queues, pair with a trip to the Jeronimos Monastery (which is where the custard was truly invented - by the nuns of the monastery who handed the tarts over to a nearby sugar shop - voila - Pasteis de Belem) and walk away the calories during the rest of the day.
