Hello! It is wonderful that you are planning a trip to Lisbon, and you are certainly in for a treat.
To help guide your search, it is useful to know a small but important detail about these pastries. Strictly speaking, there is only one place that produces authentic Pasteis de Belem, and that is the historic Fabrica dos Pasteis de Belem in the Belem district. Everywhere else in the city, these delicious custard tarts are referred to as Pasteis de Nata.
Here are the top spots to try, all of which offer exceptional quality at very reasonable prices:
1. Fabrica dos Pasteis de Belem (Belem district)
This is the original bakery that has been using the secret recipe from the Jeronimos Monastery since 1837. The pastry here is remarkably light and crispy with a smooth, warm custard. Despite its international fame, the price remains very accessible, usually around 1.40 to 1.50 euros each. Tip: The takeaway line out front can be quite long, but if you walk inside to the seated dining rooms, you can often find a table much faster.
2. Manteigaria (Multiple locations, including Chiado and Time Out Market)
Many locals consider Manteigaria to be the best overall pastel de nata in the city. They ring a bell whenever a fresh, warm batch comes out of the oven, and you can watch the pastry chefs at work through an open glass window. Their tarts have a slightly creamier filling and perfectly caramelized tops, costing around 1.30 to 1.40 euros.
3. Pastelaria Santo Antonio (Near the Castle of Saint George)
Located on the climb up to the castle in the Alfama area, this spot won first prize in Lisbon's official Best Pastel de Nata competition. Their pastry has an exceptionally flaky crust and a balanced custard infused with hints of lemon peel and cinnamon.
4. Castro - Atelier de Pasteis de Nata (Baixa / Chiado)
Castro specializes exclusively in custard tarts. They use high-grade butter and ingredients, and their shops offer a relaxed, elegant atmosphere where you can pair a fresh tart with an espresso for under 3 euros in total.
Across the city, almost all bakeries sell these pastries for between 1.10 and 1.50 euros, making it very easy to sample several on a modest budget. I hope you have a fantastic trip and enjoy tasting them all!
