Chartreuse Cocktail

I was in the mood for something bourbony after work, and on Internet Cocktail Database I came across something called the Chartreuse Cocktail:  1 oz bourbon, 3/4 oz each dry vermouth and yellow chartreuse.  Shake over ice etc.

I was rather suspicious of the recipe; I don't tend to like bourbon drinks, like the Perfect Manhattan, that call for dry vermouth.  This isn't bad though.  The flavor is very herbal, sweet, and reminiscent of Benedictine.  For bourbon, I used Four Roses' Single Barrel.  Surprisingly, not a bad cocktail.
