One of my favourite store for its style, concept and products is Merci Merci at 111 boulevard Beaumarchais, Paris. It was introduced to me by a friend last year and can't thank her enough for it. The store is an experience. Each display has a room like feel, the coffee shop is the library and the space feels like a huge warehouse-loft (if there is word like that). Outside the store is a red fiat which is their logo and their profits go to a charity organization making the store all the more lovable. Soon they will open an online store, something to watch out for.
