Restaurant prosecution mostly about nothing after dessert returned (9)
I believe the answer is:
trattoria
'restaurant' is the definition.
(type of Italian restaurant)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for trattoria that I've seen before include "Place to eat" , "where Italians eat" , "Italian restaurant" , "Italian eating establishment" .)
