Standard way of talking up trouble in gallery (5)
I believe the answer is:
prado
'gallery' is the definition.
(I know that Prado is a gallery)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for prado that I've seen before include "gallery for paintings" , "exhibits here?" , "foreign gallery" , "gallery abroad" , "Famous art gallery in Madrid" .)
