Very nice.
This weekend, I was at a friend's house who made me Mexican Old Fashioned, which was made with Mezcal, but had a splash of an Islay for smokiness. It was really good, although bitters tend to make me sick feeling if I have had more than a few drops. I'm not sure what bitters is supposed to add that's positive. I would probably like Old Fashions better if they didn't have any.
