Just to the north of Les Halles you will find this quaint, and very historical, pedestrian (mostly) only street called rue Montorgueil. It is the defining thoroughfare of the neighborhood known by the same name. Capitalizing on its centuries' old reputation of the fine foods quarter of Paris, many of the shops you find today dotting this street cater to food lovers: Lov Organic Teas, La Mère de la Famille chocolates, and other gourmet food items that are conveniently wrapped up for easy shipping.
However, once you come to the cross-street of rue Etienne Marcel, you start to get into a sort of edgy fashion area. And here you begin to find established French name brands as well as small designer boutiques. The prices in this area tend toward the reasonable so if you are up for a day of bargain hunting, this is a good area in which to start.
And just near this area, along the rue Etienne Marcel, and on rue St. Martin, you will find kitchen utensil and equipment shops that are full of everything the aspiring chef, or chef-on-the-weekends, could ever dream of wanting. One of the more famous ones is La Bovida but there are others a bit further up the street, like A. Simon, that are smaller but which do stock different inventory and a variety of cookware and bakeware items, too.
