Celebrated with a meal around opening time (5)
I believe the answer is:
feted
'celebrated' is the definition.
('fete' can be a synonym of 'celebrate')
'meal around opening time' is the wordplay.
'meal' becomes 'feed' (feed can mean food).
'around' indicates putting letters inside.
'opening' says to take the initial letters.
The initial letter of 'time' is 't'.
'feed' placed around 't' is 'FETED'.
'with a' is the link.
(Other definitions for feted that I've seen before include "Wined, dined and honoured" , "Wined and dined, celebrated" , "Lionised" , "Honoured lavishly" , "Honoured with festivities" .)
