The best grocery store around!!! And I would say in Oslo but can't as I am so new here (although I…read morehave a hunch it's the best!).
Especially if you are a foreigner like Greek, Italian, Turkish, Asian, Arabic this store is something you must know about! It has many things you can not find anywhere else. I as a Greek found Greek feta, olive oil, cheese, yoghurt, balsamic, olives and there must be more products I haven't discovered yet!! All from Greece from brands that are well known.
There are also specialties like Italian pasta, lots of Asian sauces and ingredients, beans that you don't find easily in the stores, etc. just go and try it yourself! There is something for everyone! Also the fruits are of very good quality and they have ALL kinds! Plus they have the cheapest nuts you can find. Definitely good for saving some money.
Also it is open on Sundays too until 22:00 so it is a good place to get food when the other supermarkets are closed. Enjoy!
