ANSWER: 17th Century
EXPLANATION: The first cafes of France opened in the 17th Century, precisely in the year 1660. There is a conflict with the year as some say that coffee was introduced to Paris in 1669 by Suleyman Aga and two years later in the year 1671, an American who was known as Pascal opened a coffee drinking booth at the fair of St.-Germain. The formal cafe was introduced named Cafe de Procope, which was opened by Sicilian chef Francesco Procopio dei Coltelli in the year 1686.
