If you need somewhere to contemplate leaving your lover, go alone, and if you don't mind them not being there to share something sublime in a glass or a dish, you have your answer.
I love to spend time in this museum, with great exhibitions about : fashion, graphic design, jewelry and toys. The bookshop is also really good. And basically... architecture !
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 quite special museum and soulfood in the 9th arrondissement packed with Moreau's work, who established and decorated it himself, so that his works could be gathered and displayed the way he wanted. He lived and worked there all his life long, and was ready in 1896… Two years later he died at the age of 72.
