Coffee looked at the wrong way (5)
I believe the answer is:
decaf
'coffee' is the definition.
(type of coffee)
'looked at the wrong way' is the wordplay.
'looked at' becomes 'faced' ('face' can be a synonym of 'look at').
'the wrong way' says the letters should be written backwards.
'faced' back-to-front is 'DECAF'.
(Other definitions for decaf that I've seen before include "Non-alcoholic drink" , "Less stimulating coffee?" , "Coffee without the kick?" , "Type of coffee" , "Cup substitute missing kick" .)
