Like other members of the European Monetary Union (EMU), Austria’s currency is the euro, which is divided into 100 cents. There are coins for one, two, five, 10, 20 and 50 cents, and for €1 and €2. Notes come in denominations of €5, €10, €20, €50, €100, €200 and €500.
Hotels One or two euros per bag for bellboys is sufficient. The same in top flight hotels for valet parking. Leaving loose change behind for cleaners is not expected but appreciated.
Restaurants Tip unless the service is abominable. About 10% is common, done by rounding up the bill (eg by saying zwanzig euro, bitte) or, if the bill comes in a leather folder, either by stating the amount as you hand it over or leaving the tip in the folder when you leave.
Bars About 5% at the bar and 10% at a table.
Taxis About 10%.
