Roll in bistro's terrible (6)
I believe the answer is:
roster
'roll' is the definition.
('roster' can be a synonym of 'roll')
'in bistro's terrible' is the wordplay.
'in' says the answer is hidden in the clue.
'ROSTER' can be found hidden inside 'bistros terrible'.
(Other definitions for roster that I've seen before include "List showing turns of duty" , "Duty rota" , "Roll" , "List of duties and those who are to perform them" , "Work rota" .)
