Passing across note, Calvin ordered something to drink in a Parisian bar (3,5)
I believe the answer is:
vin blanc
'something to drink in a parisian bar' is the definition.
'passing across note calvin ordered' is the wordplay.
I cannot quite understand how this works, but
'note' could be 'la' (I've seen this in other clues) and 'la' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for vin blanc that I've seen before include "French drink" , "(French) white wine" , "White wine in France" .)
