Do and Co is located right in front of St. Stephen’s cathedral, a stone’s throw from the Opera and Vienna’s best shopping streets – a really superb location. One of the smaller luxury hotels in Vienna Do and Co has a restaurant on the top floor of the hotel with stunning views. The Onyx bar is very popular, and it too has amazing views of the cathedral. The restaurant covers traditional Viennese dishes but it also specialises in sushi, sashimi and fresh fish.
