For some reason, I thought the US had a hold on "most ginormous stores omg", but this place is…read morehuge! Like IKEA or something.
It's primarily food, with a small section of department store things. To be honest, I'm not sure that it's selection is that much larger than ICA Väst. Maybe twice as many choices of jam, but a lot more of each one.
It's a ways out of town, but not too far from Flogsta. From the huge parking lot, feels like a car destination. It's also close to a Systembolaget, so you can stock up on groceries and booze on the same trip.
