Named for the well-known boulevard that cuts through Paris and into the Arc de Triumph, this cocktail was first seen in The Savoy Cocktail Book, by Harry Craddock. The original recipe was for a batch and named "Chartreuse", not Green or Yellow, as an ingredient so you'll see many variations. A riff on the Sidecar, this is an easy drink for those looking for an intro to Cognac or Chartreuse.
Very similar to the Sidecar, but swap Green Chartreuse for the Cointreau, and twice as much sweetener. I prefer the Sidecar but the complexity of the Green Chartreuse is nice here. Next time I might try with 1/4oz or 3/8oz cane sugar syrup instead of the full 1/2oz. Death & Co cane sugar syrup is 2:1 (sugar:water) as well, so a 1:1 mix might yield a really nice result. The original recipe 4.25 stars. Very drinkable and enjoyable cocktail. And strong.
