It's always good to check out what's happening in Fondation Cartier. They have lots of really good exhibitions of modern art, and the gallery itself is very beautiful. Perfect for seeing works you already know as well as discovering new artists and inspirations.
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.
A small market open Tuesday to Saturday in a beautiful hall at 39, rue de Bretagne in the 3rd arrondissement. People come here for lunch as much as for shopping. It is the oldest market in Paris and it takes its name from an orphanage, established in the sixteenth century, who collected the lost children and wore red. Especially the Japanese cookshop and the Cous-Cous are worth going there.
Not far from the center of Paris lies this fantastic art gallery. It is an astonishing building and has an amazing collection of works. The ticket you buy for the museum usually allows you free entry into the neighbouring theme park!
