Eight arranged in hotel area for meal (4,3)
I believe the answer is:
high tea
'meal' is the definition.
(I know that high tea is a type of dinner)
'eight arranged in hotel area' is the wordplay.
'arranged' indicates anagramming the letters (letters rearranged).
'in' is an insertion indicator.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'area' becomes 'a' (maths abbreviation).
'eight' anagrammed gives 'ighte'.
'h'+'a'='ha'
'ighte' put within 'ha' is 'HIGH TEA'.
'for' acts as a link.
(Other definitions for high tea that I've seen before include "A lofty kind of evening meal" , "Early evening meal" , "Late afternoon meal which includes a cooked dish" , "Late-afternoon meal" , "Early-evening meal" .)
