Drinks and a sandwich (5)
I believe the answer is:
round
I believe this is a double definition.
'drinks' is the first definition.
(I've seen this before)
'a sandwich' is the second definition.
(as in a round of sandwiches)
'and' is the link.
(Other definitions for round that I've seen before include "stage of competition" , "Regular route for a sentry" , "Ignore fractions" , "Spherical; song" , "Serving of sandwich" .)
