Fancy art deco from middle area of Paris (9)
I believe the answer is:
trocadero
'area of paris' is the definition.
'fancy art deco from middle' is the wordplay.
'fancy' is an anagram indicator.
'middle' indicates the central letters.
The middle of 'from' is 'ro'.
'art'+'deco'='artdeco'
'artdeco' anagrammed gives 'trocade'.
'trocade'+'ro'='TROCADERO'
(Other definitions for trocadero that I've seen before include "London restaurant opened by J. Lyons & Co in 1896, closed 1965" , "Battle scene" , "Area across Seine from the Eiffel Tower, decorator (anag.)" .)
