Girl gets one cold drink in India (5)
I believe the answer is:
lassi
'drink in india' is the definition.
(I've seen this before)
'girl gets one' is the wordplay.
'girl' becomes 'lass' (lass can informally mean a girl).
'gets' is a charade indicator (letters next to each other).
'one' becomes 'I' (Roman numeral).
'lass'+'i'='LASSI'
'cold' acts as a link.
This may not be right. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for lassi that I've seen before include "Indian dairy drink" , "creamy drink" , "chilled drink" , "that Indian necks?" , "Cold drink" .)
