The Sixth is a new 50-seat cocktail lounge in Lincoln Square that has been very popular since opening in late December. The Spaceman Spiff cocktail incorporates smoky cedar and citrus flavors into a mezcal-based drink. The bartenders had to stop taking a shot every time a customer commented about the neighborhood needing a place like this. The Sixth offers creative cocktail presentations and uses six different house-made ice cubes, along with a selection of spirits and beers to satisfy all patrons.
