Casino is a gambling establishment offering various types of gambling games. Some casinos also offer other leisure activities, such as restaurants, bars, and night clubs. Many casinos provide security and surveillance through cameras. Modern casinos usually divide their security force into two departments: a physical security department to patrol the facility and respond to calls for assistance and reports of suspicious or definite criminal activity, and a specialized surveillance department that operates the casino’s closed-circuit television system, known in the industry as the eye in the sky.

The casino industry is a huge global business. The most famous casinos in the world have a reputation for luxury and excitement, and they often attract celebrity visitors. The Bellagio, for example, is renowned for its iconic fountain show and its fine-dining restaurants. It is ranked among the world’s top three largest land-based casinos, even though it only occupies a small fraction of the total land mass of Winstar World Casino in Oklahoma—a state whose most famous native son is Woody Guthrie and where chicken fried steak is a staple.
