Steak done differently in French city (9)
I believe the answer is:
tournedos
'steak' is the definition.
(tournedos is a kind of steak)
'done differently in french city' is the wordplay.
'differently' indicates anagramming the letters.
'in' means one lot of letters goes inside another.
'french city' becomes 'tours' (I've seen this before**).
'done' with letters rearranged gives 'nedo'.
'nedo' placed into 'tours' is 'TOURNEDOS'.
(Other definitions for tournedos that I've seen before include "Small round thick beef fillet" , "Steak" , "Round thick piece of beef fillet" , "Pieces of beef" , "Round thick fillet cut" .)
