This subterranean beer hall is a locals' haunt and well-kept secret with occasional live accordion or violin music. When opened in 1683, soldiers were given free wine to keep them motivated to guard the city walls. Joseph Haydn is also said to have enjoyed a glass here and often asked to be paid in wine by his boss Duke Esterházy. Today they still offer cheap wine, and between 4 and 6pm the house wine is reduced to €1 a glass. The buffet-style eatery also serves a la carte, but the real fun is choosing from the cutlets, spreads, and salads at the bar. The network of caves and long rooms give it a very personal feel despite the vastness of the cellar. No one will mind if kids want to explore the caves and they'll have fun sampling the finger food and Almdudler (herbal lemonade). This is a good Inner City alternative to the more rural Heuriger wine taverns in the outer districts. There's also an upstairs restaurant called the Stüberl, with outdoor seating in summer and a traditional Austrian la carte menu.
