Abstract: A portable beverage service device may include a base, defining a central cavity, and a minor lid movably coupled to the base. An organizing divider may be disposed in the base over the central cavity. A plurality of container receptacles may be positioned on the organizing divider and may extend into the central cavity. A chest, which may define an auxiliary cavity that extends into the central cavity, may be disposed in the organizing divider. A major lid, having a lateral restraint, may be coupled to the base and may be movable between a major lid open position and a major lid closed position. The lateral restraint may be moved to a horizontal position when the major lid is in the major lid closed position, and the lateral restraint may be moved to a vertical position when the major lid is in the major lid open position.
