Topless bar is fake (9)
I believe the answer is:
imitation
'is fake' is the definition.
(imitation leather for example)
'topless bar' is the wordplay.
'topless' means to remove the first letter.
'bar' becomes 'limitation'.
'limitation' with its first letter taken away is 'IMITATION'.
(Other definitions for imitation that I've seen before include "created by the impressionist" , "Sham - mimicry" , "Simulated" , "Copy; copying" , "take-off's called for!" .)
