Eat in Joe's coffee house (5)
I believe the answer is:
scoff
'eat' is the definition.
'in joe's coffee house' is the wordplay.
'in' says the answer is hidden in the clue.
'SCOFF' is hidden in the letters of 'joes coffee house'.
(Other definitions for scoff that I've seen before include "Deride - guzzle" , "Devour (informal)" , "Ridicule - guzzle" , "Mock" , "Jeer - eat quickly" .)
