As the name implies, whiskey is the leading man at this shadowy, wood and tin-walled room in the Lower Garden District. And beer, for the beer-and-a-shot specials. If you know and love your brown liquor, the substantive selection, primarily American, Japanese, and Scottish, will blow your hair back. If you don’t, the bartenders will share their expertise. Customized flights work well for both scenarios. Reliable pop-up restaurants rotate through the kitchen.
