Yes - I was being a little facetious. Their take-away food is awful. But they do seem to specialise in nice pancake shops. Their 'national food' was something like mashed potato and cabbage....
You forgot the delights of vending machines dispensing fries (chips) with mayonnaise. That's a proper Dutch treat.
Lived in Groningen for six months - absolutely loved it. Quite small for a city though.
