An Arabic drink knocked over in Asian city (6)
I believe the answer is:
ankara
'asian city' is the definition.
(capital of Turkey)
'an arabic drink knocked over' is the wordplay.
'arabic drink' becomes 'arak' (Asian alcoholic beverage).
'knocked over' says the letters should be written in reverse.
'arak' in reverse letter order is 'kara'.
'an'+'kara'='ANKARA'
'in' acts as a link.
(Other definitions for ankara that I've seen before include "Capital of Turkey" , "Capital established by Ataturk" , "Capital city" , "Turkey's capital" , "Turkish city" .)
