Answer the following question: Given the following passage "In addition to the classical restaurants, Paris has several other kinds of traditional eating places. The cafe arrived in Paris in the 17th century, when the beverage was first brought from Turkey, and by the 18th century Parisian cafes were centres of the city's political and cultural life. The Cafe Procope on the Left Bank dates from this period. In the 20th century, the cafes of the Left Bank, especially Cafe de la Rotonde and Le Dome Cafe in Montparnasse and Cafe de Flore and Les Deux Magots on Boulevard Saint Germain, all still in business, were important meeting places for painters, writers and philosophers. A bistro is a type of eating place loosely defined as a neighbourhood restaurant with a modest decor and prices and a regular clientele and a congenial atmosphere. Its name is said to have come in 1814 from the Russian soldiers who occupied the city; "bistro" means "quickly" in Russian, and they wanted their meals served rapidly so they could get back their encampment. Real bistros are increasingly rare in Paris, due to rising costs, competition from cheaper ethnic restaurants, and different eating habits of Parisian diners. A brasserie originally was a tavern located next to a brewery, which served beer and food at any hour. Beginning with the Paris Exposition of 1867; it became a popular kind of restaurant which featured beer and other beverages served by young women in the national costume associated with the beverage, particular German costumes for beer.
