I am planning a trip to Germany this September and am looking for restaurant recommendations in Munich, Fussen, and/or Berlin. We are not looking for fancy, just good food at mid-range prices. We have found some from our Rick Steves guidebook (2019) that have closed.
In Berlin we are staying in the Rosenthaler Platz area.
We haven't been there in several years, but we think this Austrian restaurant (with unusual Austrian wines) is very nice: https://www.ottenthal.com/en/ It's higher-midrange, however. Small, and the website says air-conditioned. Check whether still cash-only.
