Where to go in for some gateaux (4)
I believe the answer is:
gate
'where' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'go in for some gateaux' is the wordplay.
'go in' becomes 'ate' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'some' says to take the initial letters.
The initial letter of 'gateaux' is 'g'.
'ate' after 'g' is 'GATE'.
'to' is the link.
Can you help me to learn more?
(Other definitions for gate that I've seen before include "Facility in airport" , "Number attending" , "Entrance to a Dublin theatre" , "It may be barred" , "Confine to college" .)
