Palatial Oxford bar is not finished - is it time to give up? (7)
I believe the answer is:
opulent
'palatial' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for opulent that I've seen before include "Rolling" , "No let-up (anag)" , "Wealthy, rich" , "'Rich, sumptuous (7)'" , "'Loaded'" .)
