Jog out of bistro, tentatively (4)
I believe the answer is:
trot
'jog' is the definition.
(I know that jog can be written as trot)
'of bistro tentatively' is the wordplay.
'of' indicates the answer is hidden within the clue.
'TROT' is hidden in the letters of 'bistro tentatively'.
'out' acts as a link.
(Other definitions for trot that I've seen before include "Jog along" , "Move quite fast" , "moderate movement" , "Run with short steps" , "Left wing" .)
