Literally the coolest bookstore I've ever seen, and I've seen plenty. This amazing store is in some kind of an old printing press / newspaper building and along with a HUGE selection of books, mags and more, plus the great coffee and desserts cafe, there is the professor upstairs who has created all kinds of electrical inventions - a Willy Wonka like character - amazing - and he gives you tours of his inventions. THIS IS NOT TO BE MISSED during your visit in Lisbon!!
