Like some humour found in Cairo, nice (6)
I believe the answer is:
ironic
'like some humour' is the definition.
(irony is a kind of humour)
'in cairo nice' is the wordplay.
'in' says the answer is hidden in the clue.
'IRONIC' is hidden in the letters of 'cairo nice'.
'found' is the link.
(Other definitions for ironic that I've seen before include "Causing wry amusement through an unexpected outcome" , "W. Country port, its Channel" , "Characterised by mildly sardonic wit" , "Perverse or sarcastic in expressing opinion (6)" , "Suggesting the opposite for humorous effect" .)
