Located just to the north of the city centre (a 20-minute or so walk from Union Square), the train station in Cluj has a variety of facilities ranging from cafes to kiosks to exchange places, although probably best to avoid the latter. The station has decent rail links to Bucharest, Budapest and Vienna, but connections to regional cities are frustratingly slow and rare. Still, there is a romance to the rails, so maybe that is what you are after.
