Sandwich and drinks (5)
I believe the answer is:
round
I believe this clue is a double definition.
'sandwich' is the first definition.
(as in a round of sandwiches)
'drinks' is the second definition.
(I've seen this before)
'and' is the link.
(Other definitions for round that I've seen before include "stage of competition" , "Encircling" , "stout" , "The canon" , "Full" .)
