With nonpareil style for the urbane host, Mixology Center reflects the cosmopolitan aplomb of its famed designer David Rockwell. Thoughtfully kitted out on its powder-coated steel frame with a rack for stemmed champagne and wine glasses above a walnut shelf for tumblers. Below, a matching wood work surface at waist level tops a wine rack shaped from burnished leather and an essential liquor cabinet with a sliding walnut door and brass hardware.
