There is a modular furniture system having at least one wall, at least two support units, and at least one counter unit. The wall unit typically has a front surface, a back surface, and at least a first support tab and a second support tab. Each of the support units is capable of being coupled or joined to the wall unit. The counter unit can then be rested upon the wall unit and support units. Any number of wall units, support units, and counter units may be used in constructing the furniture system. The wall units and counter units may be curved or straight or bear other shapes to create unique overall pieces of furniture. In some embodiments, the furniture system may manifest itself as a portable bar.
