Have you ever heard of rakiya? It’s the favorite drink of most people in Bulgaria. I can be made from plum, grape, pear, peach and so many other fruits, it’s insane.
The alcohol content can go as high as 80% and as soon as people start getting drunk (which doesn’t take very long), they play chalga or folk music and dance around in large groups.
If traditional is not really your thing, you can find very easily clubs that play from hip hop to rock. Bulgaria also has amazing pop singers always touring around the country, most times playing in free festivals.
