Unusual drink (3)
I believe the answer is:
rum
I believe this is a double definition.
'unusual' is the first definition.
(I've seen this before)
'drink' is the second definition.
(rum is a kind of drink)
(Other definitions for rum that I've seen before include "An alcoholic spirit - sounds odd" , "Odd kind of drink for sailor" , "Eerie" , "The spirit is peculiar" , "Sugar-cane product" .)
