Quickly necking booze, setter vandalised 3 hub (7,6)
I believe the answer is:
downing street
'3 hub' is the definition.
The definition suggests a singular noun which matches the answer.
'quickly necking booze setter vandalised' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'setter' is 'street' which is located in the answer.
The remaining letters 'downing' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for downing street that I've seen before include "Political location" , "The (British) government" , "gated community?" , "UK seat of government" , "PM's address -- enters, got wind (anag)" .)
