This is the best option near the Kunsthaus Wien and the Hunderwasser House. Formerly a wine tavern, it's now a revitalized, great value, down-to-earth beisl (the equivalent to a pub, also called a gasthaus). The menu changes regularly but almost always features local-favorite protein-packed dishes and Schinkenfleckerl (delicious pasta squares stuffed with ham and cabbage, best served with a leafy green salad), fine wines, and a great choice of deserts.
