Chez Jeanette is a cool bar to hang out in located on the same street where I have lived since I was two years old. Many trendy young people hang out here everyday where one can listen to good music whilst sipping nice drinks.
Among numerous art galleries in Paris, this one is seriously worth visiting. Very inspiring place with lots of great exhibitions. Yes, too much coolness and beauty in Marais can make you dizzy, but we like it, don't we?
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.
