Parking in Asian city where one used to go for cryptic advice (6)
I believe the answer is:
delphi
'where one used to go for cryptic advice' is the definition.
(as in the oracle at Delphi)
'parking in asian city' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'in' indicates putting letters inside.
'asian city' becomes 'delhi' (New Delhi).
'p' put inside 'delhi' is 'DELPHI'.
(Other definitions for delphi that I've seen before include "Greek site of Apollo's most famous oracle" , "Scene of Greek oracle" , "Scene of ancient oracle" , "Old programming language" , "Ancient Greek city, site of famous oracle" .)
