Better known as Pastelaria O Careca ('The Bald Guy') among locals, this simple pastelaria flanking a small plaza has been dishing out Lisbon's sweetest croissants since 1954. It's definitely worth heading a few blocks inland from the tourist onslaught along Belém's waterfront for the doughy, sugar-coated goodness.
It's the anchor of Rua Duarte Pacheco Pereira in Restelo, a pleasant stretch of tourist-free sidewalk cafes and restaurants.
