The Saint Michel fountain is a typical meeting place for Parisians or foreigners who then go to alleyway full with bars and restaurants: the most famous is Saint André des Arts. Close to Saint Michel is Port Royal where the Closerie Brasserie des Lilas is located: place of meeting for artists and famous writers. It is located between Saint Germain and Latin Quarter (is so called because conversation between students and professors was in Latin until the Revolution). Academia remains a focal point of life (the Sorbonne is here). It is one of the quarter’s late-opening bookshop where you can linger in a café, eat cheap in its abundance of budget restaurants or clink drinks during a dozen different happy hours.
You should visit the Panthéon, Institut du Monde Arabe, Grand Galerie de l’évolution, Musée National du Moyen Age and the Mosquée de Paris.
