In the very touristic Graça area, there is this heaven place, hidden from tourists. This café belongs to the theater da Garagem. It has an amazing view, the atmosphere is peaceful and with a lot of light. They don't have wifi if you plan to work there though..

beautiful collection from a couple of interior designers 

Off-the-beaten-path, just outside Lisbon. The best seafood! Humble and local atmosphere. Check the opening times first + Sr. Domingos doesn't open when his football team plays!

one of my favorites places to have a coffee or a drink. to work during day time or to enjoy some live music in the afternoon.

It´s the kind of place you automatically feel like you take a break from the city for a coffee or a light meal. The trendy Chiado area is just around the corner.
