We already had bad experiences with this restaurant from a visit a few years ago, but because of the new ownership we tried again. We ate in the room immediatelly at the entrance; there is also another room behind a sliding glass door, and because of the decorations we took this to be for private receptions, but only later we found out that this is the non-smoking section. There is no hint or marking and also the waiters did not tell us. The menue lists a number of well-known Viennese dishes. I ordered "Beuschel with Dumplings", i.e. lung. The dumpling was ok, but the rest was spoiled with an overdose of vinegar.
