Latte brewed in extremely suave city (7)
I believe the answer is:
Here is my best explanation:
'city' is the definition.
(Seattle is an example)
'latte brewed in extremely suave' is the wordplay.
'brewed' indicates anagramming the letters.
'in' indicates putting letters inside.
'extremely' suggests removing the centre.
'suave' with its middle removed is 'se'.
'latte' is an anagram of 'eattl'.
'eattl' inserted inside 'se' is 'seattle'.
(Other definitions for seattle that I've seen before include "city in north-west America", "Sleepless in --, film", "somewhere in Washington", "American city", "Let's eat at this US city", "US West coast port", "US west coast port", "Largest city in the state of Washington", "Port of north-west USA" and "US Pacific port".)
