The owner personally guides visitors through the roasting compound, explaining single origins and blends as he goes, in a shop with roots stretching back to an earlier address on Rua da Misericórdia.

A one-man coffee bar where the owner pulls every shot himself and will talk you through the beans if you let him. There's no food menu here, just coffee, done with real care.

People come to Copenhagen Coffee Lab & Bakery for the pastries, but the batch filter holds its own here: hot, smooth and low in bitterness. Flat whites arrive in a proper ceramic cup with a choice of milk, not shoved into a takeaway default.

Copenhagen Coffee Lab's own-roastery beans give this Bairro Alto stop a solid foundation, and reviewers keep coming back for flat whites that land right every time.

A dependable Bairro Alto & Príncipe Real stop pouring beans from two named roasters, Manhattan Coffee Roasters and Sumo Coffee Roasters, with the flat white the thing regulars keep coming back for.

A brunch spot in Príncipe Real built around açaí bowls and a food-forward crowd, but worth the stop for the coffee alone: espresso handled with more care than the menu lets on.
