Malomerice, the largerst freight train station in Brno which can be walked over. If that's not cool, then I don't know what is.
Brno is Czech's second largest city. It's a place full of peaceful country folk who drink more wine than Bohemians, their Czech friends to the west. Brno hasn't been trampled by many tourists, so it has quite a different character than the capital city, especially from the eyes of a visitor.
