Very nice place where you can take your time for a coffee or eat french cooking by a Japanese chef. The design is like you're at home and there are different artist displayed on the walls.
If you're looking for somewhere that has an an excellent selection of artist books then Yvon Lambert is the place to go. Not only that but they sell incredible tote bags, with great straps and nice minimal design that will last you a life time. Out the back is a small gallery space, often showcasing the work of featured artist who's book is for sale in the shop. One of my favourite things about this shop is how friendly and welcomign they are! Not only that but they do cool collaborations, such as the one with David Horvitz, where he emails them a new photograph of the sky every day, the bookshop prints it out and you can only buy that one image on the day.
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!
The majority of creative agencies in Paris are located along Canal Saint Martin so everyday the banks of the canal are full of artists and creative people enjoying their lunch break. If one is lucky enough to be around the canal on a sunny day its the best place to enjoy a drink.
