Coffee shop order (5)
I believe the answer is:
latte
'coffee shop order' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for latte that I've seen before include "Espresso coffee and milk" , "frothy cup" , "Espresso added to frothed steamed milk" , "Type of coffee" , "Kind of espresso coffee" .)
