Seine-Saint-Denis features a large number of shopping malls in Northeastern Paris. Some of them are open or partially open on Sundays, as well as the movie theater and restaurants.
Here is the list of malls to enjoy a shopping spree for clothes, furniture, linen or jewelry to suit any of your tastes. Each of them is located close to the main trunk road around Ile-de-France via the main highways. You will always have a train or RER station a few steps away from the mall.
Reminder: winter sales are from January 10th to February 20th.
