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.
I've interviewed curator and founder Marie Madec a couple of times now; she represents their contemporary artists with a dedication and enthusiasm that's infectious.
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.
