and no Jägerschnitzel

I've never looked, but I would have expected Spätzle further west than Munich - more BW than Bayern, it is more Swabian in my experience.

I hope you find what you're looking for ...

What about the Weihenstephan in Freising?

This dish at the airport looks close, at least:
Airbräu special plate 21,7
Three grilled medallions of pork | mushroom
sauce | crispy bacon | grilled tomato | herb butter |
cheese spaetzle

I think you will find a Jägerschnitzel (with mushrooms and sauce) in Bavaria is usually not breaded (Schnitzel natur) and will come with some type of potato. Sometimes with red/green peppers too. I associate the breaded Schnitzel with mushrooms to Hessen and Spätzle to Schwaben (western Bavaria). If you ask you can probably get what you want. I like and have to ask for a breaded Schnitzel with Pfifferling mushrooms and sauce when I see they are on the menu, but not together. You usually have to pay a few more euros for it. Unique but sometimes on the menu is a breaded Schnitzel with a black pepper sauce. A little like a KFC Schnitzel. You don't see it too often. A local place here has it with Spätzle too.

Hotel Gastof Maisberger has an excellent restaurant and is just 10 minutes away on the S1 line. Exit at Neufahrn and the hotel is immediately outside of the station.

I would have expected Spätzle further west than Munich

I agree that Spätzle originated in Schwaben and is more common there, but I think it is far more ubiquitous today. The first time I had Spätzle in Germany was in Garmisch-Partenkirchen.
And I've had Käse Spätzle in Zell (Mosel), which is far west of Schwaben.

Thanks for all of your helpful suggestions. I lived in the Rheinland-Pfalz area of Germany for 4 years a very long time ago. Jagerschnitzel and Spatzle was my favorite dish then. I know I've had it in Munich, too. I even make the spatzle at home. You can get the spatzle makers on Amazon for about $10.

I have a very long layover in Munich on the way back from Italy - and wanted to make the best of it. That's what I thought of. The timing of the layover is mostly overnight, so not much will be open and it will be dark most of the time. I was thinking that if I spent the night in Freising, I could perhaps have dinner, and then get up early for a walk around the old town before heading back to the airport. The Hotel Gastof Maisberger would be quicker and cheaper to reach, but I think I'd have to give up the idea of a walk around Freising in the morning. I'm looking into that, though. I could even spend the night right at an airport hotel and have dinner at the airport restaurant - but that would not do much for my Germany nostalgia. At least I now know of options, though.

The area around Hotel Gastof Maisberger is very walkable. We enjoyed walking through the town. Our stay at the hotel was great and we would gladly go back.
