I'll be spending my a few days of my holidays in Vienna and I found the city quite dead today (24th). It was such a disaster to find a nice restaurant to have dinner and every single shop/restaurant was closed. I'd like to know a few breakfast/brunch cafes to have a breakfast tomorrow (25th). Could anyone recommend some places to have a breakfast/brunch on Christmas holidays?
In Vienna, the Christmas holiday is celebrated in homes, and most restaurants and shops are closed from December 24 to December 26. Traditionally, the biggest observation is on Christmas Eve, the 24th, the official public holidays and closures are on the 25th and 26th. As Christmas Eve is the big event, some places have opening hours on the the following two days (e.g., museums, cinemas, clubs).
Usually Vienna Tourism/Wien Turismus, a service of the Vienna Tourist Board, lists restaurants open on the 24th, district by district (currently the 2017 coverage).
The independent Vienna Unwrapped, in its Christmas Dinner and Christmas Day In Vienna 2017 article, suggests heading to hotels with restaurants, along with tips on what attractions are open (sightseeing, markets, concerts).
