Blokes with posh food list (4)
I believe the answer is:
menu
'food list' is the definition.
(I've seen this before)
'blokes with posh' is the wordplay.
'blokes' becomes 'men' (bloke can informally mean a man).
'with' says to put letters next to each other.
'posh' becomes 'u' (abbreviation for upper-class - opposite to non-U).
'men'+'u'='MENU'
(Other definitions for menu that I've seen before include "Restaurant fare" , "List of fare" , "Carte du jour" , "List of (computer or food) items" , "Card" .)
