I love to go to this library and often work there. It is very peaceful and the setting is beautiful. The library is a mine for books about design and architecture.
A paradise for a rest : waterfalls, restaurants and bars (crazy parties at the top of the hills in Rosa Bonheur) As soon as the sun is shining people are going there to share a drink or a meal, lying on the grass surrounded by blazing green.
The most fantastic selection of old toys and kid's memorabilia, better than a museum. Is there every version of every action figure ever made? I've received gifts of a 1950s Peter Pan penknife and an original ET ring from here, so now some lucky friends get presents from the huge range.
Two wellknown japanese cafeteria, close to the Louvre and the Palais Royal. Gyoza and Lamen served all day long. The one Rue St Anne is more traditionnal, chiefs are cooking in front of you. Often packed, in case there is a long waiting line, go to the one Rue St Honoré, you will eat the same!
