... or bits cooked in a small restaurant (6)
I believe the answer is:
bistro
'small restaurant' is the definition.
(I've seen this before)
'or bits cooked' is the wordplay.
'cooked' indicates anagramming the letters (letters cooked into a new form).
'or'+'bits'='orbits'
'orbits' is an anagram of 'BISTRO'.
'in a' acts as a link.
(Other definitions for bistro that I've seen before include "Modest restaurant" , "Small French bar and restaurant" , "Cheap restaurant" , "somewhere to eat" , "Small inexpensive eatery" .)
