A charcoal holding grate is provided and is adapted to be removably mounted on the support member when in a position of use and further adapted to be receivable in the open top base along with the collapsed support member for storage therein. A food holding grill is also provided and adapted to be removably mounted on the support member when in a position of use and spaced upwardly from the charcoal holding grate. The food holding grill is also adapted to be receivable in the open top base along with the collapsed support member and the charcoal holding grate for storage therein. The base has a sufficient depth to permit the cover to cover the open top to thereby permit a storage of the collapsed support member, the charcoal holding grate means and the food holding grill means within the base. If desired, a charcoal collecting member may be provided and adapted to be removably mounted in the open top base below the charcoal holding grate when in the position of use.
