Abstract: A portable bar capable of having its customer counter either slid backward and the overhanging portion pivoted downward or, alternately, completely removed from a base cabinet in order to allow the portable bar to reduce in width in order to allow it to be rolled through a standard size door frame. The base of the portable bar has a lighted work surface, top opening ice storage bin, and a slanted tower for dispensing cold beer or other beverages on tap. The base of the portable bar also has concealed storage for a CO.sub.2 gas bottle, one or more kegs of beer or other beverages, a weight measuring system for indicating the amount of beer or other beverages remaining within each keg, electrical and water supply connections, a refrigeration unit and a liquid waste storage system.
