BEST COFFEE IN PARIS: CAFÉ OBERKAMPF
Of all the coffee I tasted while in Paris, it's definitely the one I liked the most. Oberkampf Cafe is a very small space located in the 11th arrondissement in Paris near Oberkampf metro station.
I had a double espresso which was very tasty and well executed.
My suggestion: take your coffee to go because the space becomes crowded real fast and they don't take any reservations.
