Abstract: A portable, modular service cart that is readily converted to a refreshment center, game table or vanity is disclosed. The cart generally comprises a mobile unit having a horizontal tray and legs extending downward from corners thereof. The legs have casters located at lower ends thereof and comprise telescoping members for permitting adjustment of tray height. The tray has an upper surface with a sink and multiple wells provided therein, with some or all of the wells being removable and/or refrigerated. A collapsible faucet extends beyond the upper surface of the counter and includes a first end that extends over the sink and a second end that rests beneath the upper surface of the counter and is coupled to a water supply line. The water supply line is connected at an opposite end to a continuous, endless water source such as an outdoor faucet or spigot. A water filtering system is preferably secured to one of the legs of the mobile unit.
