Really hot cafe, door guards going around (2,5)
I believe the answer is:
de facto
'really' is the definition.
(thesaurus)
'hot cafe door guards going around' is the wordplay.
'guards' says the answer is hidden in the clue.
'going around' is a reversal indicator.
'otcafed' is hidden in the letters of 'hot cafe door'.
'otcafed' back-to-front is 'DE FACTO'.
(Other definitions for de facto that I've seen before include "In fact (whether by right or not)" , "Actual, not legal (situation)" , "actually" , "In practice" , "In reality, actual" .)
