I'm about to head off to Europe for almost a month - flying into and out of Brussels. My last day/night will be in Brussels and I want to go to either De Heeren or 3F. I'll be staying close to the Midi station. It is a Saturday if that matters. Which of these two would be best to go to if I can only pick one? I won't have a car and will have to take trains if that can help decide.
