Ban from pub (3)
I believe the answer is:
bar
This clue is a double definition.
'ban' is the first definition.
(I've seen this in other clues)
'pub' is the second definition.
(both are drinking establishments)
'from' acts as a link.
(Other definitions for bar that I've seen before include "Pub; block (access)" , "Prohibit; counter" , "Inn" , "Prohibit - drinking place" , "Ingot" .)
