Some reached a café, back or front (6)
I believe the answer is:
facade
'front' is the definition.
(I know that facade is a type of front)
'some reached a cafe back' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'back' is a reversal indicator.
'edacaf' is hidden in the letters of 'reached a cafe'.
'edacaf' written backwards gives 'FACADE'.
'or' acts as a link.
(Other definitions for facade that I've seen before include "Deceptive outward appearance" , "Showy front" , "ballet" , "Sitwell/Walton piece" , "piece by Walton" .)
