Fernet and coke is a very popular drink in Argentina. I had never heard of it until I got to Mar del Plata, Argentina. I was staying in a hostel (Hostel La Playa Grande), and two guys (Martin and Jorge)there drank this every night. I tried a drink of it and it is pretty strong stuff. I would say that the closest thing that I have had to drink like Fernet is jagermeister. The only other place that I have seen this drink is in Spain where there is a lot of Argentines living there. They also have a different flavor of Fernet, and it is called Fernet Menta. It has a very strong mint taste. Try Fernet and Coke when you travel through Argentina!
