Some love it, some hate it. Even if you have to choke down the medicinal-minty taste, you'll be feeling good after a few of these. Argentina's Travel Guide talks about the history, uses and imitators of Fernet Branca. Although my first impression was not favorable, I actually grew to enjoy a few Fernet Cokes on a night out.

A friend who visited me in BsAs found it disgusting and asked the bartender to add cherry juice to improve the taste. This did not help.
