When it comes to buffets, there's the all-you-can eat variety and the furniture variety. The latter is a type of table often found in a dining room and used to hold food platters during a meal. Buffets typically come with compartments and drawers designed to hold plates, utensils, and other serving ware.
Most often, this furniture piece is placed against the wall to the side of the dining table. For that reason, a buffet is also sometimes called a "sideboard."
