Located underneath the Hauptbahnhof inside the old first- and second-class waiting rooms, this is a deliciously ornate and classy affair with lots of wood panelling, original Art Deco lamps and free copies of the German edition of the FT. Half posh restaurant, half relaxed bar, there’s something quite magical about this place, despite it being somewhat snobby and the fact that a glass of mineral water will set you back €4. A good spot for a drink before nipping next door to their equally enjoyable club. Check the website for more details.
