Gents perhaps in Tel Aviv (3)
I believe the answer is:
lav
'gents' is the definition.
(gents toilet or lavatory)
'in tel aviv' is the wordplay.
'in' indicates a hidden word.
'LAV' can be found hidden inside 'tel aviv'.
'perhaps' acts as a link.
(Other definitions for lav that I've seen before include "Private place in short" , "toilet" , "Loo" .)
