One of the few authentic places left in downtown is the Schneider Bräuhaus: https://www.schneider-brauhaus.de/en/home-en/

Also good is the Augustiner: https://www.braeustuben.de/en/premises/#bierhalle (one of the few breweries in town)

In spite of a substantial population of Russian origin, Munich really has no typical restaurant. The Georgian place called 'Iveria' has bloody good food from the caucasus: Georgian Restaurant in Munich | IVERIA (Our Russian friend took us there once )
