Where you go when you're out for the night? (3,4,2,3)

'where' is the definition.
The definition suggests a singular noun which matches the answer.

'go when you're out for the night?' is the wordplay.
I cannot quite understand how this works, but
'go' could be 'do' (doing is a kind of going) and 'do' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

'you' is the link.
