Let's talk Kaiserschmarrn for a second here. If you're in Vienna for any extended length of time, you should get into Kaiserschmarrn. They're essentially a soft, fluffy pancake shredded to bits and served with powder sugar and some form of fruit preserves, typically stewed plums. They're REALLY good for breakfast, and this joint may just have the best Kaiserschmarrn there is. More than that, it has got a tremendous variety of them.
Among the many permutations they offer, I find the Topfenschmarrn (soft, fluffy, mild of taste) plus sour-cherry stew to be the best combination, far superior to the typical Schmarrn with plum preserves you get elsewhere. I also like the one with apples and cinnamon sugar, though a large serving size of that one will put your pancreas to work some serious overtime. They do offer a small serving size (which is, more or less, what other restaurants pass as "regular" size), but the large is twice as much goodness for only two more euros, so that's the choice of champions.
The crepes are very good, too. I had the one with ground venison with bacon and liked it a lot; it was generously furnished with meat and very tasty, with a nice tang to it. I also had a couple of baked crepes (one was ground beef with peppers, the other was ham and sour cheese cream), which, though highly enjoyable, were not as memorable as the venison. I also had a phenomenally good sweet crepe with Topfen, raisins, and vanilla sauce, which just about proved that you come here for the sweets, first and foremost.
Service varies from barely friendly to friendly, but they have been very good for the most part. Paradoxically, it seems they are in a better disposition when the restaurant is busier. Outdoor seating is just decent; indoors, you get some nice music. Business hours are also fantastic, especially in the context of the Vienna late-night food scene. They also offer tremendous value, as their food is tasty and VERY plentiful for very low prices.
