On a buffet line, whether in a restaurant, banquet hall, or cafeteria, it is important to keep cold foods cold so that they stay fresh and edible for patrons. The easiest way to do this is to have a food table that can sit on a tabletop so that you are sure that salads, veggies, fruits, and desserts maintain cool temps. The Cambro line of Cold Food Bars, which are made from polyethylene, will be sure to last for years of use and keep foods cold for hours.
