Métro: Cour Saint-Émilion (line 14)
Address: Cour Saint-Emilion - 75012 Paris
Hours: everyday 11 am - 9 pm
Restaurants are opened until 2am.
You will find boutiques for all your needs: cooking, decorating, design, clothes, sports as well as a giant bookstore (FNAC) and lots of cafés/restaurants. My favorite store is Oliviers & Co where you can find the best truffle oil and my husband could spend hours at Boardriders.
The "terrasses" (decks) are where people enjoy a drink in the shades of those fabulous buildings and it's really affordable (that's my favorite part). There is also a megacomplex movie theater. So it sounds like the perfect way to spend an afternoon: shopping, movie and a dinner.
