Famous inn: meet to get pickled (7)
I believe the answer is:
eminent
'famous' is the definition.
(eminent can mean famous or influential)
'inn meet to get pickled' is the wordplay.
'to get pickled' indicates anagramming the letters.
'inn'+'meet'='innmeet'
'innmeet' anagrammed gives 'EMINENT'.
(Other definitions for eminent that I've seen before include "Respected; outstanding" , "Important" , "Lofty; famous" , "Outstanding or distinguished (7)" , "High" .)
