reports that at Kaffi Költ in Akureyri, you can order what is called "angry coffee". Costing 50 ISK more than regular coffee, it is exactly the same as regular coffee in every way - except in its presentation.
As can be seen in the video of the RÚV article, angry coffee is served with the barista scowling. A cup is filled with coffee, and then it is brusquely thrown down on the counter, resulting in much of the drink spilling onto the counter.
Angry coffee is, however, to be taken as entertainment, says Magnús Þór Eggertsson, one of the owners of Kaffi Költ. He adds that serving angry coffee takes finesse - thrown too hard, it can splash onto people's clothing. Not hard enough, and the effect is lost.
While the method wastes a lot of coffee, Magnús says angry coffee is taken with good humour, and plenty of people are happy to pay an extra 50 ISK for the experience.
A coffee house in Akureyri has introduced a new type of coffee, which involves tossing it angrily onto the counter, with the intent of spilling it.
