Pie, counterintuitively, for each working cafe -- OK? (1,5,2,4)
I believe the answer is:
a piece of cake
'pie counterintuitively' is the definition.
I can't judge whether this definition defines the answer.
'each working cafe ok?' is the wordplay.
'each' becomes 'apiece' (synonyms).
'working' indicates an anagram.
'cafe'+'ok'='cafeok'
'cafeok' anagrammed gives 'ofcake'.
'apiece'+'ofcake'='A PIECE OF CAKE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for a piece of cake that I've seen before include "... easy thing to do" , "Breeze" , "What one may eat at a birthday party" , "Something easily achieved (informal)" , "picnic?" .)
