Dry outside facility providing meal service (3,3)
I believe the answer is:
tea set
'meal service' is the definition.
'dry outside facility' is the wordplay.
'dry' becomes 'tt' (abbreviation for teetotal).
'outside' means one lot of letters goes inside another.
'facility' becomes 'ease' (I've seen this before).
'tt' enclosing 'ease' is 'TEA-SET'.
'providing' is the link.
(Other definitions for tea set that I've seen before include "Set of crockery for serving light meal" , "hot drink service" , "Crockery service" , "Equipment for an afternoon meal" , "Estate (anag) - service" .)
