Hotel bid, eager, shows on reflection what food should be (6)
I believe the answer is:
edible
'what food should be' is the definition.
(I know that food should be edible)
'hotel bid eager shows on reflection' is the wordplay.
'shows' indicates the answer is hidden within the clue.
'on reflection' says the letters should be written in reverse.
'elbide' is hidden within 'hotel bid eager'.
'elbide' backwards is 'EDIBLE'.
(Other definitions for edible that I've seen before include "Safe to eat" , "Eatable" , "Fit to consume" , "OK for eating" , "description of fare" .)
