A tabletop food tray support apparatus uses a number of support booms stacked axially upon a post. Each boom has a tray supporting platform at one end of a rigid beam and a bearing structure at the other end. The bearing rotatably and removably engages the post so the tray-carrying platform can revolve about the post. The platform attaches to the beam in an offset manner a radial distance beyond the center of gravity of the tray so that a heavier pot will tend to deflect the platform safely toward the post thereby discouraging accidental dumping of the food tray by overloading the boom and/or by rapidly revolving the platform In this way the angled platform provides a centripetal force component to a revolving tray carried on the boom. The platform can be formed from a steel ring sized to support common serving tray shapes. The post can be made hollow to accommodate insertion of an umbrella pole therethrough for use in patio tables. The booms can be of varying lengths to reduce interference among axially adjacent booms.
