Largely bustling bar, base in city (8)
I believe the answer is:
brisbane
'city' is the definition.
(Brisbane is an example)
'largely bustling bar base' is the wordplay.
'largely' means to remove the last letter.
'bustling' becomes 'brisk' (I've seen this before).
'bar base' becomes 'bane' (I can't justify this - if you can you should give a lot more credence to this answer).
'brisk' with its final letter removed is 'bris'.
'bris'+'bane'='BRISBANE'
'in' is the link.
Can you help me to learn more?
(Other definitions for brisbane that I've seen before include "test venue" , "port" , "Aussie location" , "Strange bairns be in Oz" , "Queensland's capital" .)
