That sounds good wispy. Sadly the nearest chippy to me is a bit too far for them to be got upon my return, which means eating them in the car. And all that grease and vinegar makes it somewhat smelly.
However, the notion of a noce piece of crispy cod, flaking off in your finges does sound good and I suppose I could find a park bench.
I have some homegrown pickled onions I could take along.
