I found the delicious "Drink-Yoghurt Nature Hazal" from Lanz last Thursday in the Center Brügg.
Let's hope that the not-so-sweet, slightly sour, refreshing drink is well received so that it doesn't remain a one-day wonder.
I had to pat myself on the back for getting a glass - without it I would have slurped off the 1-liter brique, which would have been empty within seconds.
