Sadly in the UK the tradition of fish and chips in a wrap of newspaper on the way home from the pub is dying out but can still be found in the smaller towns where ethnic takeaways haven't taken over.
Fish,chips,scraps ( the bits of fried batter left over ) and mushy peas all liberally doused in salt and vinegar.Yabbadabbadoo !
You also sometimes still get the seafood sellers who tour the pubs selling cockles,whelks,mussels and fish sticks.
Eels in South London.
Deep fried Mars Bars in Glasgow.

Yes,we know how to eat well !
