Lagers I ordered in north African port (7)
I believe the answer is:
algiers
'north african port' is the definition.
(I've seen this before)
'lagers i ordered' is the wordplay.
'ordered' is an anagram indicator.
'lagers'+'i'='lagersi'
'lagersi' with letters rearranged gives 'ALGIERS'.
'in' acts as a link.
(Other definitions for algiers that I've seen before include "North African capital" , "NW African capital" , "N. African port" , "Capital city" , "North African port" .)
