A delivery apparatus includes a container for holding an article to be delivered and a heater, and an enunciating device for displaying temperature conditions within the container. The container includes a plurality of walls forming an interior area and an opening, wherein the opening is provided with a size sufficient to allow movement of the article and the heater from outside the container to within the interior area of the container. The container includes a flap for selectively covering and uncovering the opening to allow access to the interior area of the container. The heater is constructed and arranged for placement within the interior area of the container and is provided for heating the article. The enunciating device includes a temperature sensor for sensing temperature within the container, a temperature display for displaying temperature conditions within the container, and a power source for operating the enunciating device. A method for delivering food and an enunciating device are provided.
