Date leaves for tastier dinner, we hear (4)
I believe the answer is:
time
'date' is the definition.
(period of time)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for time that I've seen before include "Spell" , "The father of Truth, presumably" , "See 1 and 21" , "> moment" , "Indefinite period" .)
