While Vienna's coffee house scene is legendary, if you're staying someplace in the Innere Stadt, finding a breakfast can be a bit challenging.
Up rides Haas & Haas to the rescue. You want a Viennese breakfast of cafe mit schlag and a pastry? They'll do that. A British breakfast of tea, beans, egg, and toast? They'll do that. American with an omelette? Yes. A "Breakfast for two" of salmon, brioches, pan fried egg and ham scramble, and prosecco? How about a Chinese style breakfast with fried rice and dim sum? Funny you should ask...
The quality is consistently high. The place is well-hidden, in a corner of the Stephanplatz. The crowd is a mix of tourists and very proper Viennese ladies.
What more could one ask?
