Meet in French bar (9)
I believe the answer is:
encounter
'meet' is the definition.
(I know that meet can be written as encounter)
'in french bar' is the wordplay.
'in french' becomes 'en' ('in' in French).
'bar' becomes 'counter' (I've seen this before).
'en'+'counter'='ENCOUNTER'
(Other definitions for encounter that I've seen before include "Unexpected meeting" , "Run into - combat" , "Meet unexpectedly" , "Meet by chance with encore nut" , "fight" .)
