Seafood Roy's arranged around empty table (6)
I believe the answer is:
oyster
'seafood' is the definition.
(oyster is a kind of seafood)
'roy's arranged around empty table' is the wordplay.
'arranged' is an anagram indicator.
'around' means one lot of letters goes inside another.
'empty' means to remove the middle letters.
'table' with its centre taken out is 'te'.
'roys' anagrammed gives 'oysr'.
'oysr' placed around 'te' is 'OYSTER'.
(Other definitions for oyster that I've seen before include "taken in by carpenter" , "Capital card" , "Source of natural pearls" , "person unwilling to communicate" , "one got out of bed?" .)
