Banquet carts come in a number of sizes. The smallest can hold a few dozen plates, while larger carts can transport 200 or more meals. These carts are built with external temperature gauges that let staff monitor internal temperatures to ensure that your guests' meals are being held at the ideal temperature. Thermostatic controls allow users to adjust that temperature when needed. Many banquet cabinets also feature built-in humidity systems that help keep food at its ideal texture as it's transported to diners' tables.
