Bar meeting the needs of Europeans on vacation? Incredible! (9)
I believe the answer is:
forestall
'bar' is the definition.
(thesaurus)
'meeting the needs of europeans on vacation? incredible' is the wordplay.
'meeting the needs of' becomes 'for' (for a purpose).
'on vacation?' suggests removing the centre (I've seen 'on vacation' mean this).
'incredible' becomes 'tall' (as in a tall tale).
'europeans' with its centre taken out is 'es'.
'for'+'es'+'tall'='FORESTALL'
(Other definitions for forestall that I've seen before include "Stop" , "Hinder by anticipation" , "Arrive first" , "Check" , "Obstruct by taking advance action" .)
