Enjoy European drink outside first - it's fantastic (9)
I believe the answer is:
dreamlike
'fantastic' is the definition.
(thesaurus)
'enjoy european drink outside first' is the wordplay.
'enjoy' becomes 'like' (like can mean to appreciate or enjoy something).
'european drink outside' becomes 'dream' (I am not sure about this - if you are sure you should believe this answer much more).
'first' is a charade indicator (letters next to each other).
'like' after 'dream' is 'DREAMLIKE'.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for dreamlike that I've seen before include "Imagined" , "Illusory" .)
