Small restaurant, snack bar (4)
I believe the answer is:
cafe
This clue is a double definition.
'small restaurant' is the first definition.
(I've seen this in another clue)
'snack bar' is the second definition.
(thesaurus)
(Other definitions for cafe that I've seen before include "Place to eat" , "Coffee shop" , "Inexpensive restaurant serving light refreshment" , "snacks served here?" , "Coffee house" .)
