In addition to providing gamblers with an opportunity to test their luck, casinos can also provide other forms of entertainment such as concerts and dining options. Many casinos are part of a larger complex that features hotels, restaurants, conference rooms and even spas. This type of casino is called a mega-casino. These casinos are often very expensive, but they are able to attract high-rollers because of their impressive offerings.
There are no clear figures on how many people visit casinos worldwide, but the industry is estimated to be worth around $270 billion. In the United States, the largest casinos are located in Las Vegas and Atlantic City, while other well-known gaming destinations include Macau and Singapore. The most famous casinos have a long history and are known for their luxurious amenities. For example, the Bellagio in Las Vegas boasts a branch of the prestigious Le Cirque restaurant and Hermes and Chanel boutiques.
