Really hot cafe, door guards going around (2,5)
I believe the answer is:
Here is my best explanation:
'really' is the definition.
'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 "Really", "Actually", "In fact (Latin)", "actually", "Actual, though maybe not legal", "Actual, not legal (situation)", "In practice", "In fact (whether by right or not)", "effective" and "In reality, actual".)
