Bar in the Flamingo Tavern (5)
I believe the answer is:
ingot
'bar' is the definition.
(thesaurus)
'in the flamingo tavern' is the wordplay.
'in' indicates a hidden word.
'INGOT' is hidden in the letters of 'flamingo tavern'.
(Other definitions for ingot that I've seen before include "Mass of metal, especially gold or silver" , "Bar, brick of metal" , "Moulded metal bar" , "Block (of steel, gold, etc)" , "Piece of precious metal" .)
