Rectangular chafing dishes are used more than any other shape of chafer out there. With such a wide selection available, pick the exterior design that best fits your table. They range from economy lines to units that are designed for formal and fancy events. The biggest issue with chafing dishes is where to put the lid when the guest is serving themselves. They are hard to hold when serving yourself, and no room on the table to set it down. Consider a chafer with a hinged or roll-top lid, so that the chafer does all the work. Also, some chafers have a holder on the back for holding the lid.
Rectangular models are perfect for keeping food warm at the buffet. There are a variety of products available. Most rectangular chafers fit a full-sized food pan. Look in the associated products to find the food pan to match your chafer. When choosing a chafing dish, metal type, capacity and cover type are the most important features to look for. Most chafers are stainless steel, but many have gold, brass, chrome or even silver accents.
