- Currency
- Euro (€). Cards work almost everywhere — but several excellent Beisl are still cash only , and they will not warn you until the bill.
- Emergency
- 112 for everything · 133 police · 144 ambulance.
- Time zone
- CET / CEST — same as Germany.
- Power
- Type C/F sockets, 230V — German plugs fit.
- Language
- German, with a distinctly Viennese vocabulary. English is widely spoken. Greet with "Grüß Gott" rather than "Hallo" and you will be read as making an effort.
- Getting around
- The U-Bahn, trams and buses share one ticket, and the 24/48/72-hour passes are excellent value. Buy before boarding and validate once — there are no barriers, but inspectors are frequent and fines immediate. For actually getting around: U-Bahn is fastest for crossing the city (roughly 20 minutes end to end), but tram lines 1 and 2 are the ones worth taking on purpose — they run the length of the Ringstrasse and pass most of the grand sights along the way, so the ride itself is part of the sightseeing. Buses mainly serve the outer suburbs; most visitors touring the centre won't need them.
- Airport transfer
- The CAT (City Airport Train) is the fast, nonstop, pricier option to Wien Mitte. The S7 suburban train covers the same route in 23-25 minutes for a flat €5.40, stopping at several useful points along the way (Wien Rennweg, Praterstern, Handelskai) rather than running express — genuinely better value unless the few extra minutes matter more than the price difference. If you already hold a Wiener Linien day or weekly pass, the S7 only needs a small supplementary ticket for the airport-to-city-boundary stretch.
- Tipping
- Round up, roughly 5–10%. Tell the waiter the total as you hand over the money rather than leaving coins on the table — that is the local mechanism, and leaving cash behind can read as odd.
- Coffee houses
- A UNESCO-listed institution. You order one Melange and may stay for three hours with a newspaper, and nobody will hurry you — that lingering is the product. Do not order a "latte"; ask for a Melange , Verlängerter or kleiner Brauner .
- Meal times
- Lunch 12:00–14:30 , dinner from 18:00 . Kitchens in traditional Beisl often close by 21:00.
- Closing days
- The thing that ruins itineraries here: many of the best Beisl close Sunday and Monday , and some open only Wednesday to Saturday. The Kunsthistorisches closes Mondays outside summer. Check before building a day around one.
- Sundays
- Shops are closed by law , as in Germany. Museums, cafés and restaurants stay open, and the parks fill up.
- Tap water
- Piped from Alpine springs and genuinely excellent — Vienna is rightly proud of it. Free public drinking fountains all over the centre.
