When I want to enjoy a beer in the open air, but also have a great meal, I often head to
Sankt Emmeramsmühle. The menu is on the pricier side, but the food far exceeds the usual beer garden fare. The salads are especially good, and Sankt Emmeramsmühle has one of my favorite Brotzeitteller services. In fact, this is one of the few beer gardens that does not have self service- you have to order your beer and food from a waiter or waitress.
Sankt Emmeramsmühle is also one of those beer gardens that is best reached by bicycle. There are not a lot of parking spots, and although there is a nearby tram stop, it's a very pleasant ride through the Garden or along the Isar to reach the beer garden.
Lastly, if you're wondering who the heck St. Emmeram is (as I was), I went ahead and did a little research for you: turns out he was a Frankish bishop from Regensburg who suffered a gruesome death (involving being bound to a ladder and tortured and hacked to pieces) when he voluntarily covered for a woman who bore a child out of wedlock, claiming the child to be his in order to mitigate her shame... Reportedly, after St. Emmeram died his body was floated up the Isar to Regensburg, and the current site of the St. Emmeramsmühle in Munich is where the journey of his floating dead body began.
So there you have it.
