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.
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.
