Cheese lovers don't miss this shop!!! I often buy cheese there. Even if their stand is relatively small, they have a very wide range of cheese selection. Aside cheese they also sell natural yogurt, real milk I mean not the 300% skimmed milk that some shop sell :-) and some fresh bread.
Service is always friendly and willing to help selecting the right "one" for you. It's also quite well located in the Im Viadukt Markt (between Limmatplatz and Escher-Wyss platz). You can reach it with trams 4, 13 and 17 and step out at Dammweg tramstop.
Give it a try, it's worth it read more
