Car takes a right into the drink (7)
I believe the answer is:
martini
'the drink' is the definition.
(martini is a kind of drink)
'car takes a right' is the wordplay.
'car' becomes 'mini' (Mini Cooper).
'takes' means one lot of letters goes inside another.
'right' becomes 'rt' (abbreviation as in Rt Hon- the Right Honourable).
'a'+'rt'='art'
'mini' going around 'art' is 'MARTINI'.
'into' acts as a link.
(Other definitions for martini that I've seen before include "tipple" , "Italian drink" , "Type of Italian vermouth" , "Gin or vodka with dry vermouth" , "alcoholic drink" .)
