Mabillon Cafe is open 22 hours a day. This is a lounge bar in the heart of Saint-Germain, which is usually home to locals in heels. During the day, the large terrace attracts passers-by in search of sun relaxation. A glass with Chablis in hand, sunglasses in place in any weather, here you can see and see. When happy hour rolls around, golden youth grab leather banquets to sip cocktails. For those looking for a bite to eat, you can get a croque monsieur, a salad seam or a cheeseburger at any time, even at rather overpriced prices. This is one of the few places that is still open at 4 AM, so it's a great hideaway for a place to fill up after a big night.
