It is one of the nicest grocery stores in Helsinki. Anton & Anton in Kruununhaka is a small but extemely well equiped, bright and inviting place. Here you get everything from fresh meat, cheese and bread to organic fruits, vegetables, jams, pasta, sauces, teas, candies and much, much more.
The friendly staff also gladly helps you to find whatevery you are searching for. The focus on Anton & Anton is clearly on quality rathern than on quantity. Their approach of course has an effect on the prices here. Be prepared to pay a bit more than in a normal supermarket. But the visit here is definitely worth it.
You can also find Anton & Anton in Töölö and in Ullanlinna. For more information check out their website.
