Cambro portable beverage bars are designed for the various needs of caterers and hotel and event venue managers. They range from the most basic economy models, equipped with ice bin and storage space, to complex models with a fully-equipped bar system including cold plates, soda guns and CO2 lines. The 540 series is even designed to fit inside an elevator or door jamb for even better mobility. The 730 and 650 series are larger bars that are made for larger-scale bartending.
