A Sweet Manhattan served on-the-rocks with added herbal complexity and an all-important splash and dash or two of New Orleans bitters.

The Benedictine and extra bitters really pack a punch, in a very good way, and as the drink diluted with ice I thought it only improved. Drink makes me feel like I should be smoking a cigar and talking politics. Will be bookmarking this in my favorites category.
