Poetic paradise (6)
I believe the answer is:
xanadu
'poetic paradise' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for xanadu that I've seen before include "ideal place" , "where pleasure-dome was planned" , "old Chinese summer capital" , "pleasure centre?" , "Where Kubla Khan built his pleasure dome" .)
