The specialty coffee roaster locals send their friends to first. Two Porto locations, but the Sá de Noronha café is the one to work from — small downstairs, but the upstairs has a communal table that's been quietly co-opted by remote workers and rarely fills before midday. Single origins on rotation, fast WiFi, and they don't time you out. What to order: Flat white made with whatever Tanzanian or Guatemalan single origin they have on bar that day, and a cinnamon roll if it's before noon.
