Sample decor in the Greek city (7)
I believe the answer is:
corinth
'greek city' is the definition.
(I've seen this before)
'sample decor in the' is the wordplay.
'sample' indicates the answer is hidden within the clue (I've seen this in other clues).
'CORINTH' can be found hidden inside 'decor in the'.
(Other definitions for corinth that I've seen before include "Greek Gulf, isthmus city" , "Ancient Greek city" , "City of Greece" , "Mediterranean port" , "Region of ancient Greece" .)
