a more precise set of munich recommendations:
in the morning:
laugendreieck and pretzels (hopefully fresh - i think the long ones called laugenstangerl are better than the traditional ones) from galeria kaufhof (in the basement food area, off of Marienplatz). personally i think laugendreieck are a worth a dedicated trip, but more conveniently, all the rischart shops are reliable for traditional breads and pastries (many train stations have kiosks).
lunch or dinner:
at either augustiner stammhaus (when you enter, i prefer to avoid the host, go to the right, and sit at one of the communal long tables but there is also a courtyard in the back) or hofbrauhaus (both next to marienplatz)
the most classic and essential thing you can get is a schweinshaxe (pork knuckle/hock with crispy skin). schnitzel at either place is also good. avoid the pretzels at either place. beer: at augustiner, edelstoff; at hofbrauhaus, the basic original. desserts at augustiner are meh, at hofbrauhaus, the dampfnudel is very good - similar to a tres leches.
if you like asparagus, it doesn’t get any better than fresh white asparagus from bavaria. early june will be at the very tailend of the season, but you might still be able to find it. both beerhalls will do solid versions of it, but you might try to find a fancier place for dinner that might feature it more (maybe the restaurant at dallmayr, although i cant vouch for their quality myself). ideally, you’d just buy it fresh from the market next to marienplatz and cook it yourself…
and then if you have a second day, i would recommend altin dilim (in the previous recs), and potentially an exploration of dallmayr - a very fancy grocery store. notably you can find some very outstanding cheeses at dallmayr from across europe.
