The Jungfrau in winter can be said to be cold and windy. We were so cold that we couldnt stand it, so we went to the restaurant in Jungfrau to eat something to add heat. The variety of restaurants is fairly complete, and not too expensive, each package is almost 10-20CHF, enough for one person. We ordered a sausage set with Swiss characteristics, which is super delicious and highly recommended! In order to warm our stomach and increase the calories, we also bought a small bottle of Whisky, 40% VOL, and drank it in my mouth. I felt a heat flow from my mouth to my stomach. After a while It was all over the body, and the two of us who had been frozen on the snowy mountain finally slowed down.
