Bud sent up excellent state (5)
I believe the answer is:
dubai
'state' is the definition.
(I've seen this before)
'bud sent up excellent' is the wordplay.
'sent up' is a reversal indicator.
'excellent' becomes 'ai' (resembles 'A1', old-fashioned term for excellent).
'bud' reversed gives 'dub'.
'dub'+'ai'='DUBAI'
(Other definitions for dubai that I've seen before include "Gulf territory" , "One of the UAE and its capital" , "Gulf city/state" , "capital and port" , "Persian Gulf state" .)
