Time Out says
Situated in the bohemian neighborhood of Dreimühlenviertel, Gaststätte Großmarkt boasts what many locals consider to be the finest Weisswurst in town. Tucked away in a less-touristy corner, it provides for a truly authentic Munich experience. To do it properly, come for breakfast, and enjoy the fine taste of a proper sausage while taking in the equally fine sounds of the rich Bavarian dialect filling the space around you.
Time Out tip: Make sure to have your Weisswurst before noon! This is because in the days before refrigeration, the sausages were freshly prepared and would go bad if left around in the afternoon. To this day, it’s considered proper in Munich to have Weisswurst only before the noonday bell tolls.
