When I am off, I really enjoy chilling and sipping a nice cup of coffee by the River. A few metres away from Le Louvre Museum, at the bottom of Pont Neuf, there is a friendly coffee shop which offers a fantastic view over the Seine River, Ile de la Cité, Ponts des Arts and the Eiffel Tower, and where the staff is helpful and friendly (not too common in Paris).
The wooden tables and chairs are laid out on a deck outdoor terrace with nice wild plants here and there ; it's just lovely.
Later on during the day, they serve home-made dishes, cheese and cold cuts boards. Perfect for a drink by the river.
Down 16 quai du Louvre (at the feet of Pont Neuf) - 75001 Paris
