Though most can't pronounce it, everyone in Vienna knows about this spot. Franz Kafka lived next door to this first branch and used to come here for sandwiches and beer. Serving only open-face sandwiches, it's unlike any buffet you've seen, with six or seven cramped tables and a rapidly moving line of people, all jostling for space next to the glass counters. Indicate to the waitress the kind of sandwich you want. Most people hurriedly devour the delicious finger sandwiches, which come in 18 different combinations of cream cheese, egg, lox, salami, herring, tomatoes, lobster, and many other tasty ingredients. You can also order small glasses of fruit juice, beer, or wine with your snack.
