- Situated in the heart of the Castle District, this historic coffee house and patisserie has been open since 1827. It was founded by Franz Schwable and bought by Wilhelm Ruszwurm in 1884. It was nationalised under the Communists but is now run by Istvan Lukacs, ever since it was given back to its pre-war owner. The tiny coffee house comprises two small rooms, the first of which has a glass cabinet at one end from where you can select a pastry or cake. The walls are lined with more glass cabinets, all filled with such treasures. The second room has space for customers to sit on elegant light green chairs which evoke the splendour of the Austro-Hungarian Empire. All manner of coffees can be sampled and an interesting item on the wall is an ancient drinks list which shows what the beverages of preference were in the days of Maria Theresa. The cakes are delicious and the service is excellent.
