Perhaps “boiled beef in broth” doesn’t sound quite as alluring as its German name of Tafelspitz. Yet Tafelspitz was the preferred meal of Emperor Franz Joseph, and it remains a favorite Viennese dish. There’s one establishment, Plachutta, that has cornered the market on fine Tafelspitz; the eponymous gastronome Mario Plachutta has raised his preparation of the modest rump cut served with roasted potatoes, minced apples, and horseradish to a gourmet level. The main restaurant sits on the popular Wollzeile shopping street just a block from the Ringstrasse, but the chef has also built a mini empire of jade-toned Plachutta restaurants—including one in a lovely Biedermeier cottage and another near the Schönbrunn Palace in Hietzing.
