Those Coke dispenser dispenses outside Arkansas city (7)

'city' is the definition.
(I have seen 'Spanish city' mean 'linares' so perhaps 'city' could also mean 'linares')

'those coke dispenser dispenses outside arkansas' is the wordplay.
I cannot really see how this works, but
'arkansas' could be 'ar' (abbreviation for the US state) and 'ar' is found in the answer.
'coke' could be 'line' (a line of cocaine) and 'line' is located in the leftover letters.
A single letter 's' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
