The best fish and chips on the East Coast?

Quite possibly when the weather is like today.
We parked in the forest and walked to Walberswick for coffee (and cake), then onto Dunwich across the marshes for the fish and chip lunch. Then back part of the way across the marshes and then through the heathland to the forest car park.
11 and a half miles all told although the walking was easy and no hills were encountered - maximum altitude 60 ft above sea level!
