The Ghent Festival at night...

This is the set up at night - bars bars bars (but no horribly drunk people), all clustered around stages. This one looks over the river to the World Music Stage which is the epicentre of the Festival - then the other stages are dotted around the old town.  Like the one below...

And there are food places everywhere...in addition to the cafes/bars making extentions to their premises and putting on their own parties. 

This is a good way to see it (check out the video)
