'coke in new york' is the definition.
'blow' can be an answer for 'coke' (I've seen this in another clue). I am unsure of the 'in new york' bit.

'after opening of bottle down' is the wordplay.
'after' is a charade indicator (letters next to each other).
'opening of' suggests taking the first letters.
'down' becomes 'low' (associated in meaning).
The first letter of 'bottle' is 'b'.
'b'+'low' is 'BLOW'.
