Cold and hot dish in take-away outlet (7)
I believe the answer is:
chippie
'take-away outlet' is the definition.
The definition suggests a singular noun which matches the answer.
'cold and hot dish' is the wordplay.
'cold' becomes 'c' (eg on taps).
'and' says to put letters next to each other.
'hot' becomes 'hip' (both can mean fashionable or trendy).
'dish' becomes 'pie' (I've seen this before).
'c'+'hip'+'pie'='CHIPPIE'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for chippie that I've seen before include "food shop" , "character in fast-food outlet" .)
