Café Schwarzenberg said to be the oldest café on the Ringstrasse, is known for its opulent interior and wide selection of Viennese coffees. Severely damaged during the post-war occupation, it was renovated in 1979. The highlight is the hot chocolate 'Alt Wiener Art' with cinnamon, vanilla, and whipped cream. Travelers praise the café for its authentic atmosphere, friendly service, and great food. It is described as a perfect place to relax, read a book, and experience the traditional Viennese coffee culture. Despite its popularity, the café doesn't appear overcrowded with tourists. Expect queues at peak times.
