ounded in 2008 by Raymond Nisi, Lucky Metalios and Jonathan Stern, Double Helix Bar + Double Helix Boutique launched its first dual bar and boutique concept at The Shoppes at the Palazzo in Las Vegas. The name, Double Helix, was carefully chosen to reflect the positive and proven benefits of wine on human health, and hence, structural DNA. Double Helix Bar + Double Helix Boutique is a unique Las Vegas wine bar and wine retail concept located in The Shoppes at The Palazzo. The 450,000-square-foot luxury destination retail center at The Palazzo-Resort-Hotel-Casino is on the famed Las Vegas Strip between The Venetian and Wynn. The Palazzo location is the first venture for Double Helix.
