Ladies perhaps in Tel Aviv (3)
I believe the answer is:
lav
'ladies' is the definition.
(the ladies' lavatory)
'in tel aviv' is the wordplay.
'in' indicates the answer is hidden within the clue.
'LAV' is hidden in the letters of 'tel aviv'.
'perhaps' is the link.
(Other definitions for lav that I've seen before include "toilet" , "Loo" , "Private place in short" .)
