Eat in various coffee houses (5)
I believe the answer is:
scoff
'eat' is the definition.
'in various coffee houses' is the wordplay.
'in' indicates the answer is hidden within the clue.
'SCOFF' can be found hidden inside 'various coffee houses'.
(Other definitions for scoff that I've seen before include "Jeer; eat greedily" , "Greedily consume" , "Mock" , "food on offer" , "Devour (informal)" .)
