ABSTRACT:
A serving tray having multiple levels includes a lower tray, a tapered collar, a cylindrical extension and an upper tray. The lower tray has a receiving cup having a ribbed exterior surface for alignment to one end of the tapered collar in a non-rotatable manner. The cylindrical extension is sized to fit through the other end of the collar and into the receiving cup such that rotatable movement of the extension is permitted. The upper tray has a centrally located cup with a vertical wall that extends below the planar surface of the upper tray and fits within the upper end of the extension so that the upper tray rotates with the extension.
