Serve someone attractive (4)
I believe the answer is:
dish
'serve' is the definition.
('dish' can be a synonym of 'serve')
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for dish that I've seen before include "stunner?" , "Satellite aerial" , "Vessel for food" , "Plate and what's served on it" , "something in the oven?" .)
