I have no memory of this edit (7 years ago). It might have been based on a previous note. While I know the terrace of shops, I haven't been there for 30 years. I may have actually been in the apartment upstairs. :)

There exists in Ireland, and likely in other places, shops that are the size of a (sometimes large) convenience store, but do not stock convenience items. They can not be described as supermarkets, as they do not have, e.g. cleaning, hygiene or pet food items. 

They typically stock 'dry' food (limited or no fresh vegetables, limited frozen foods) and other products from a particular culture, e.g. delicacies, newspapers, possibly some clothes, and seasonal / festive items. They may provide money transfer and/or international telephone cards.

In Ireland, most of these shops are aimed at the eastern European, south and east Asian or to a lesser extent, African and Caribbean communities. There will also be halal, kosher or equivalent shops.

I suspect many such shops are tagged as "shop": "asian_food_shop", "shop"="food", or "shop"="yes".

In places outside Ireland and especially in the UK and USA, some supermarkets will have an "Irish section", which would be an equivalent.
