Drink is quite wrong before the French dawn (7,7)
I believe the answer is:
tequila sunrise
'drink' is the definition.
(I've seen this before)
'quite wrong before the french dawn' is the wordplay.
'wrong' indicates anagramming the letters.
'before' is a charade indicator (letters next to each other).
'the french' becomes 'la' ('the' in French).
'dawn' becomes 'sunrise' (synonyms).
'quite' is an anagram of 'tequi'.
'tequi'+'la'+'sunrise'='TEQUILA SUNRISE'
'is' is the link.
(Other definitions for tequila sunrise that I've seen before include "Multicoloured cocktail" , "Cocktail - 1988 American crime film - equaliser units (anag)" , "cocktail's required" , "Drink" .)
