cape town

I'm a little stuck... Click here to teach me more about this clue!

'sa location' is the definition.
I can't tell whether this definition defines the answer.

'can we opt out?' is the wordplay.
'out?' is an anagram indicator (out can mean wrong or inaccurate).
'can'+'we'+'opt'='canweopt'
'canweopt' is an anagram of 'CAPE TOWN'.

Can you help me to learn more?

(Other definitions for cape town that I've seen before include "Port under Table Mountain" , "place in South Africa" , "foreign city" , "Port city in South Africa" , "Oldest S Afr. city" .)

I've seen this clue in The Telegraph.
