Favorite Vienna cafes?

I quite like the Hawelka in Dorotheergasse just off Graben in the city center. It oozes history, the service is refreshingly grumpy and there is a good selection of newspapers available.

Other than that Cafe Landtmann is quite alright, too.

My favourite is Café Diglas in the Wollzeile, just behind the Stephansdom. Very authentic atmosphere and excellent food. Medium-priced. Here you can have a look:

Cafe Schwarzenberg is beautiful. It's located on the Ringstrasse and is a great way to spend a rainy morning.

It isn't a coffee cafe like Landtmann or Hawelka, but if you get a chance drop by the Trznewski sandwich shop just off the Graben (look up, you'll see a sign) They have fantastic open faced sandwiches, generally with egg salad and a host of maybe 50 other things, kept neat and tidy by a fleet of waitresses wearing hankies in their pockets. You can point and order one or two and a pfiff of beer, which is the cutest little glass stein about 1/8 the size of a regular stein. Just enough to wash down a small sandwich or two. The place is unique to Vienna and a great treat. Enjoy.

I loved taking breaks at celebrated Demel (Kohlmarkt 14), a confection in itself of mirror and Venetian glass. We thought it deserved its reputation. Have the hot chocolate or einspanner coffee, and strudel or other pastries. You go up to the pastry case to choose what you want. A few other light foods like salads are available, but that’s not the reason to go. Location very central.

I really enjoyed the Griensteidl, which is about as central as you can get, and has an "old Vienna" feel. Good coffee, good lunch food, good service, and free newspapers. Avoid the Korb - they tried to short-change me.
