Which food-sellers look like a Cockney? (8)
I believe the answer is:
butchers
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for butchers that I've seen before include "Meat shop (look!)" , "Look (slang) - Smithfield Market workers" , "kills cruelly" , "Retailers of meat" , "Animal killers in Schubert composition" .)
