I had not been in Coop Karma at the train station in Zug for so long that I never noticed the amazing zero-waste wall they have at the back of the shop.
I did not have much time to look into the details (particularly the origin of the various grains, in order to check whether the prices take this into account) but the range of options seems good enough (different grains, dry beans, cereals, rice and nuts), and you will also find minimalistic containers to do your shopping.
I will seriously look into this as a source of food shopping for specific items - unfortunately taking the train to find a shop like Chez Mamie in Zurich is counter-productive if I can find both packaging-free food and cosmetics in town. I will update you here when I start.
