Gastwirtschaft Blauensteiner is a popular neighborhood restaurant in Vienna's District 8, where the historic Josefstädter Straße sets off (across from it, Cafe Eiles, is another legendary establishment). Creaky floors, a well-earned patina in both of the high-ceilinged halls. Most of the heavy wooden tables are taken up by regulars, judging by their rapport with the not especially accommodating waiter.
My go-to starter here is always the pork in aspic (Sülze), fully coated in red onions and doused in sunflower oil (your best chance to convert your friends to this disappearing delicacy). The tender and moist egg dumplings (Eiernockerl) are notably excellent, both with bright-tasting salad or as a side dish. Close out with the chestnut-filled dumplings dessert (Maroniknödel). Mains are €13-18. Nota bene: excellent weekday lunch menu; also open on weekends; cash only!
