Anyone who regularly orders a Martini rarely just orders a Martini. They have the specs for the drink they want in their head, and they tell the bartender how they like it.
The Rusty Nail is an old man drink, but it’s a much younger one than, say an Old Fashioned or a Manhattan.
The Vieux Carré is what it would look like if the Manhattan had an eccentric, worldly, New Orleanian great aunt.
It’s rich and spirit forward with a split base of rye and cognac.
