On our flight from Copenhagen to Prague, we had an 8 hour layover in Brussels which was the perfect amount of time to do a quick tour of the city. Brussels is really small so we saw the main attractions, got Chris a Belgium beer and ate frites and gouffres (waffles). We also went to the history museum and found the Mannequin Pis - I don't understand the fascination of it but it was funny to take pictures of people taking photos with it. I think 8 hours was plenty of time to get a quick tour of what Brussels is like but if we ever get the chance, we may visit again if we were nearby. Regardless of size, Brussels certainly doesn't lack any of the European charm other cities have!
