How some café is served (2,4)
I believe the answer is:
au lait
'how some cafe is served' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for au lait that I've seen before include "Like cafe drink" , "With milk in France, say coffee" , "White" , "Milk added" , "With milk (French)" .)
