Port served with Indian dish, then seconds? (9)
I believe the answer is:
baltimore
'port' is the definition.
(I've seen this before)
'indian dish then seconds?' is the wordplay.
'indian dish' becomes 'balti' (I've seen this before).
'then' is a charade indicator (letters next to each other).
'seconds?' becomes 'more' (I've seen this in another clue).
'balti'+'more'='BALTIMORE'
'served with' acts as a link.
(Other definitions for baltimore that I've seen before include "Large city in Maryland" , "City of north Maryland" , "US city" , "City north-east of Washington DC" , "Largest city of Maryland, USA" .)
