Rue Cler, Paris
This is a two or three block long pedestrian area where you will find lots of markets, shops, and restaurants. There are many of these in Paris, but it seems that most tourists like this one. I will admit that it is more upscale than the one in my neighborhood and Davoli's is a wonderful store not to be missed if you are there, but I have never managed to go over there in the morning when all the people are doing there shopping. If you are visiting Les Invalides or the Eiffel Tower you might want to stop here and pick up something for lunch or have a coffee.
The rue Cler (7° arrt) is one of the streets markets of Paris.
Only a part of the street is dedicated to the market. So it seems a bit short and has less interest than rue Mouffetard and Rue Montorgueil (see my Travelogues about these streets).
You will find there mainly food shops (meat, fish, delicatessen, fruits, vegetable, chocolate, etc.).
RUE CLER MARKET:
If you're at the Eiffel Tower make your way down Rue de Grenelle to Rue Cler, a traditional Parisian neighborhood with all the necessary shops -- wine, cheese, chocolate, bread, a bank, and a post office. When the market is open, this is the place to assemble your picnic lunch.
