I booked a table for us outside directly on the Danube. We want to support the Viennese gastronomy these days. After the lockdown they need business. As our meetup was before the pandemic also in restaurants I thought we go back there, then.
We have to test regularly anyways, especially if you are not vaccinated. It's not over yet. There we will be registered as guests and wear the mask as soon as we need to go to the toilet, that's it.
