nemorina79. Thanks for that great advice, know nothing about cafe culture in Vienna, and this information is very useful in helping us to distinguish between two cafe types that you have mentioned.
Will pencil in your suggestion and make our way there.
Jokoko. Surprised to see you also :-) and thanks for the tips.
We're going next August, and taking in central Europe at an alarming rate - kind of itinerary that my fellow posters on Ireland forum would shout "noooooooo...." - but we're taking in a few long relaxing stays at he end.
Its just a broadstroke trip to get a sense of travel by rail.
My wife had mentioned cafe Central as an option, so that answers the question. Vienna in the winter must have been a fantastic experience - bet you got some terrific photographs.
Is there anything specific that we should not miss (probably loads) that comes to mind ?
Thanks again!
