I have tried so many Pasteis Nata but this is still my favourite place. 

interesting and exciting art exhibitions

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..

There are not many full of green parks in lisbon, this is a quiet botanical garden that i usually go to read a book and be around dark green plants.

A medical research center in Lisbon by Indian architects Charles Correa Associates has a curved stone form with circular cut-aways.
