At Elixir, the $25 Jimmy Mac cocktail (built around an 18-year Macallan scotch) is accompanied by Gläce Luxury ice, which is a single ice sphere—for slower melting—crafted from bubble-free, double-distilled water. If that sounds a little hoity-toity, consider that the bar has roots going back almost as far as the gold rush, and that despite all its national accolades, it still bills itself as a neighborhood saloon.
