Setter at home after dog food from Chinese restaurant (4,4)
I believe the answer is:
chow mein
'food from chinese restaurant' is the definition.
'chow mein' can be an answer for 'food' (chow mein is a kind of food). I am not sure about the 'from chinese restaurant' bit.
'setter at home after dog' is the wordplay.
'setter' becomes 'me' (the setter of the clue).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'after' is a charade indicator (letters next to each other).
'dog' becomes 'chow' (chow is a kind of dog).
'me'+'in'='mein'
'mein' after 'chow' is 'CHOW-MEIN'.
Can you help me to learn more?
(Other definitions for chow mein that I've seen before include "Chinese-style dish of shredded meat(s) and fried noodles" , "Chinese-American dish" , "Chop suey with noodles" , "Chinese food" , "Hi cowmen, fancy a Chinese dish?" .)
