The Casino de Montréal is a casino located on the Île Notre-Dame in Montreal, Quebec. It is the largest casino in Canada, and one of the ten largest in the world. The casino consists of three linked buildings. Two of these, the French Pavilion and the Québec Pavilion, were built for Expo 67. The third building is an annex built by the casino. The main building has six floors, in addition to the annex and the secondary building (with four floors). Within the three structures there are over 4800 slot machines, 150 gaming tables, Keno facilities and large number of speed lotteries and virtual games. The casino also contains four restaurants, four bars, a cabaret, and meeting and banquet facilities. The casino is world-famous for being somewhat unconventional; there are windows in many places, and low ceilings. The casino is open twenty-four hours a day, seven days a week to patrons aged 18 and older. It has been a non-smoking casino since July 2003, and the former smoking lounges were closed in May 2006 with the passing of a new provincial law. Alcoholic beverages are prohibited in the playing areas. The casino's address is "1 Avenue Casino" .
