Bloke having lemon sole in the end (4)
I believe the answer is:
dude
'bloke' is the definition.
(I have seen 'American bloke' mean 'dude' so perhaps 'bloke' could also mean 'dude')
'lemon sole in the end' is the wordplay.
'lemon' becomes 'dud' (both can mean a poor example of something).
'in the end' suggests the final letters.
The last letter of 'sole' is 'e'.
'dud'+'e'='DUDE'
'having' acts as a link.
(Other definitions for dude that I've seen before include "Man (US colloq.)" , "American bloke" , "City slicker" , "Stylish and confidant man" , "Man (American slang)" .)
