Restaurant has a certain atmosphere (4)

I believe the answer is:

aura

'a certain atmosphere' is the definition.
(aura can mean an atmosphere or mood)

'restaurant has' is the wordplay.
'has' says the answer is hidden in the clue.
'AURA' is hidden within 'restaurant'.

(Other definitions for aura that I've seen before include "Intangible essence emanating from a person" , "Glorious glow" , "distinctive impression" , "Intangible air or quality" , "Atmosphere, quality" .)

I've seen this clue in The Guardian.
