I found in Rust, Austria. To be exact it was a homemade version of the "Winzer Café Conrad" located at the Rathausplatz in Rust in a really beautiful old house. The coffee and the wine are good too, but the Nusskipferl* is in my opinion the best they offer (beside the fantastic view and location and nice staff).
*pastry filled with nuts. In case you were wondering. Sorry forgot to mention it before.
