The number of cafeterias in Rex has been increasing extensively over the past few years. Cafeterias are present in office buildings, schools, colleges, hospitals and residence halls, to name a few. Cafeterias offer a range of snacks, beverages, meals, desserts, entrees, and packaged food products. They also offer breakfast, lunch and dinner. Many of the cafeterias also offer Wi-Fi hotspots, which allow visitors to browse the internet for free while enjoying the food. As a cafeteria features no table service, it is an easy and effective option for the management. In most cases, the catering at the cafeteria is contracted out to a third party company.
