I've said this before and I'll say it again: #Vienna's #Hauptbahnhof is how you do a train station. Bustling and crowded but not crammed, efficient but not hectic, clean but not sterile, with plenty of spots to sit and eat and drink and shop and wander around, but at the same time with the option to make a beeline to your train with seconds to spare before it departs. https://en.wikipedia.org/wiki/Wien_Hauptbahnhof
