From its creaky floorboards to its scuzzy carpets and ever-teetering piles of books, this legendary locals' fave is a great place to peruse a cornucopia of used tomes. It's the ideal spot for a rainy-day browse through subjects from dance to the occult. Check the windows for posters of local readings and artsy happenings around the city.
A few steps in from the door, look out for the travel section. It's ideal for picking up a guidebook to 1983 Lisbon, just in case you're a time-traveler planning a trip.
