Feasts (7)
(Another definition for regales that I've seen is " Treats".)
'feasts' is the definition.
('banquet' can be a synonym of 'feast')
This is all the clue.
(Other definitions for banquets that I've seen before include "Ceremonial feasts" , "Ceremonial dinners" , "Ceremonial meals" , "Fancy feasts" , "spreads" .)
