Drunk heading back round a Cafe's front for food (5)
I believe the answer is:
tacos
'food' is the definition.
(I've seen this before)
'drunk heading back round a cafe's front' is the wordplay.
'drunk' becomes 'sot' ('sot' can be a synonym of 'drunk'**).
'heading back' shows that the letters should be reversed in order.
'round' is an insertion indicator.
'front' indicates taking the first letters.
The first letter of 'cafes' is 'c'.
'sot' written backwards gives 'tos'.
'a'+'c'='ac'
'tos' going around 'ac' is 'TACOS'.
'for' acts as a link.
(Other definitions for tacos that I've seen before include "pancakes" , "Snacks" , "Mexican wraps" , "Mexican tortillas with various fillings" , "Foreign dish" .)
