Part of banquet here -- almost heavenly (8)
I believe the answer is:
ethereal
'heavenly' is the definition.
('ethereal' can be similar in meaning to 'heavenly')
'part of banquet here almost' is the wordplay.
'part of' indicates a hidden word.
'ETHEREAL' can be found hidden inside 'banquet here almost'.
(Other definitions for ethereal that I've seen before include "Fine" , "Impalpable" , "Airy or supernatural" , "'Fairy-like, delicate (8)'" , "Extremely delicate and light, not of this world" .)
