Restaurant UNO & U-One Bar

Restaurant UNO

The restaurant UNO in the ARCOTEL Kaiserwasser combines the two culinary styles “vegan” and “beef” in an exciting new way, and allows these two contradictory concepts meet each other in a duel of delight, in keeping with our concept “vegan vs. beef”. From meals without any animal produce at all, or the finest beef specialities, our kitchen chef and his team provide that special something.

With a colourful mix of styles ranging from vegan dishes and hearty beef specialities created by our kitchen chef, the Restaurant UNO will spoil your senses. In summer, we’d be delighted to reserve a table for you on our Kaiserwasser Terrace!

Every Sunday we have a juicy roast for you and your family, also to take away.


The U-ONE Bar is a cosy meeting place in Vienna where you can end a successful day just the way you like it. Come to live sports broadcasts, the daily happy hour or learn more about the world of spirits at a cocktail workshop.

Our bartenders will always mix you your favourite drink!
