In establishment serving drinks, another empty bottle (6)
I believe the answer is:
carafe
'bottle' is the definition.
(carafe is a kind of bottle)
'in establishment serving drinks another empty' is the wordplay.
'in establishment serving' becomes 'cafe' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'drinks' indicates putting letters inside.
'empty' means to remove the middle letters.
'another' with its middle taken out is 'ar'.
'cafe' placed around 'ar' is 'CARAFE'.
Can you help me to learn more?
(Other definitions for carafe that I've seen before include "keeper of wine" , "Source of wine" , "Wine server" , "Open-topped glass flask" , "in which one has wine?" .)
