When in Vienna, it's hard to refuse its famous schnitzel, a thin cutlet of veal that is breaded and fried, usually served topped with lemon and a side of potatoes. (Note: Schnitzel Wiener Art, meaning "Viennese Style", is made from pork.) It's thought to have been brought to Vienna by Field Marshall Radetzky after returning from northern Italy in the 1850s.
Plachuttas has several locations around Vienna serving classic Viennese dishes in a fairly modern atmosphere. This location around the corner from the Opera offers outdoor seating, with heat lamps coming out for cooler evenings.
