Small restaurant in Sca Fell (4)
I believe the answer is:
cafe
'small restaurant' is the definition.
(I've seen this before)
'in sca fell' is the wordplay.
'in' indicates the answer is hidden within the clue.
'CAFE' is hidden within 'sca fell'.
(Other definitions for cafe that I've seen before include "Alate" , "Small eating place" , "Inexpensive restaurant serving light refreshment" , "Coffee shop" , "Small informal restaurant" .)
