This is a small but elegant lounge bar that features big, overstuffed leather armchairs and serves great martinis made with flair by Jocquim. What makes the Onyx an especially worth a visit is the live music. It is like experiencing a concert in your living room. We caught Jared Barry of the Moonshine Sons playing covers of contemporary songs and old rock classics. It is the ability to create small intimate spaces while sitting in an massive casino that make the Red Rock Resort someplace special.
