For example, our fondue comes from Lenk (Bernese Oberland). Some of our ice creams are Hasli-Glace (Bernese Oberland East region).
All chicken and turkey meat now comes from Switzerland. We no longer source corn from Asia, but now from Italy. You see, it's not always regional 😉
Our chief-cook is personally very motivated to do something against food waste. For example, he processes leftover potatoes into gratins (for the next day) or creates a vegetable soup, so that practically everything can be used.
