Capital hotel: what every pop star wants? (5)
I believe the answer is:
hanoi
'capital' is the definition.
(Hanoi is an example)
'hotel what every pop star wants?' is the wordplay.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'what every pop star wants?' becomes 'anoi' (resembles 'a No. 1', as in a No. 1 song).
'h'+'anoi'='HANOI'
(Other definitions for hanoi that I've seen before include "foreign city" , "Vietnamese city" , "Capital city of Vietnam" , "Asian capital on the Red River" , "capital out East" .)
