This is a very pleasant café that includes a pastry shop (Konditorei) and a restaurant. The cakes are gorgeous and will make you understand why the café is famous. The décor is fairly new, given the very long history of the place (it was called after Louise von Toscana, the run-away princess that divorced the King of Saxony). The terrace is very beautiful and overlooks the river and the famous "Blaue Wunder" bridge, real name Loschwitzer Brücke or König-Albert-Brücke. Generally it's full of locals, on Saturday afternoons, who come and chat.
