Known on the street as Cantina das Freiras, this small, sunny cafeteria inside a Catholic association is run by sweet nuns dressed as lunch ladies. They dish up a daily soup (the gazpacho is great), several mains of the beef, sardines or codfish variety, and fresh fruit for dessert. The river views from the sun-drenched terrace are astounding. Buzz 'Self-Service' for entrance.
Your meal is free on your birthday!
