Wait on a table, taking each new dish — entrées only (6)
I believe the answer is:
attend
'wait on' is the definition.
(eg a servant attends or waits on someone)
'a table taking each new dish entrees only' is the wordplay.
'entrees only' indicates taking the first letters (entre can mean a starter).
The first letters of 'table taking each new dish' is 'ttend'.
'a'+'ttend'='ATTEND'
(Other definitions for attend that I've seen before include "Be present or appear at" , "minister" , "Wait upon or be present" , "Take part in" , "Watch" .)
