Iranians belting out aria for the locals (4)
I believe the answer is:
inns
'locals' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for inns that I've seen before include "travellers' accommodation" , "Old hostelries or pubs" , "Old-time hostelries" , "drinking haunts" , "Locals" .)
