Pacino first to salute unbeatable service here in France (6)
I believe the answer is:
alsace
'here in france' is the definition.
(region of France)
'pacino first to salute unbeatable service' is the wordplay.
'pacino' becomes 'al' (Al Pacino).
'first to' indicates taking the first letters.
'unbeatable service' becomes 'ace' (I've seen this before).
The first letter of 'salute' is 's'.
'al'+'s'+'ace'='ALSACE'
(Other definitions for alsace that I've seen before include "part of France" , "Riesling-producing region eastern France" , "French region bordering Germany and Switzerland" , "Region of France, capital Strasbourg" , "French ------ -Lorraine, was German 1872-1919" .)
