Bubbly came in, or a hot drink (9)
I believe the answer is:
americano
'hot drink' is the definition.
(type of hot drink)
'bubbly came in or a' is the wordplay.
'bubbly' indicates an anagram (I've seen this in other clues).
'came'+'in'+'or'+'a'='cameinora'
'cameinora' is an anagram of 'AMERICANO'.
(Other definitions for americano that I've seen before include "drink" , "Style of coffee" , "Espresso diluted with hot water" .)
