Caught song about celebration in restaurant (9)
I believe the answer is:
cafeteria
'restaurant' is the definition.
(I know that cafeteria is a type of restaurant)
'caught song about celebration' is the wordplay.
'caught song' becomes 'caria' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'celebration' becomes 'fete' (fete is a kind of celebration).
'caria' placed around 'fete' is 'CAFETERIA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for cafeteria that I've seen before include "dining-room" , "Where one scoffs" , "Self-service eating place" , "where food is served" , "Canteen" .)
