Wine, vaults, and wienerschnitzels. Viennese taverns are not really bars but restaurants where you can stuff yourself with delicious no-nonsense food and drink local wine. Either underground, or in heurigers (winemakers’ own local taverns). Expect simple comfort food and surprisingly good cheap housewines. And from time to time, awful local music.
And if you are not acquainted with Austrian wines, try a Riesling or Grüner Veltliner from Kamptal, or any -auslese (sweet dessert wines).
