In companies in Sweden people would be up in arms if the 'fika paus' was abandoned. At about 10am and 3pm Sweden comes to a halt when its workforce leave their computers, abandon meetings and conference calls to head to the 'fika' room (yes there is a specific room for this) and happily tuck in to whatever cake a colleague has baked or bought along with a couple of cups of coffee. Across Sweden you will find endless cafes with delicious cakes, a few classics are Princess Cake (prinsesstårta), Vanilla Heart (vaniljhjärta) and Cinnamon buns (kanelbullar).
Traditionally, fika requires sweet, baked goods, there is even a book in Sweden called 'Sju sorters kakor', which means seven kinds of cakes and that most Swedes will have in their homes. Traditionally, you should serve seven different kinds of cakes and cookies if you have guests.
According to Wikipedia, the word is an example of the back slang used in the 19th century, in which syllables of a word were reversed, deriving fika from kaffi, an earlier variant of the Swedish word kaffe ("coffee"). From fika also comes the word fik (a colloquial term for "café") through a process of back-formation.
