Rene's Würstelstand, located on Vienna's elegant Schwarzenbergplatz, specializes in spicy sausages. The meats themselves are regular, but customers can request that they be smothered in the homemade chili sauces of proprietor René Kachlir. The spice level of the default "curry" sauce is perfect for my taste, but adventurous eaters can ask that he ratchet up the heat. Mr. Kachlir's sausages and sauces proved so popular that they're now also sold under his own label at Billa, the local supermarket chain. Note that opening hours are a bit inconsistent and that Rene's is closed on the weekends.
