New restaurant, outwardly ready for crockery (6,3)
I believe the answer is:
dinner set
'for crockery' is the definition.
(I've seen this before)
'new restaurant outwardly ready' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'restaurant' becomes 'diner' (diner is a kind of restaurant).
'outwardly' is an insertion indicator (some letters go on the outside).
'ready' becomes 'set' (set can mean ready or prepared).
'n' going inside 'diner' is 'dinner'.
'dinner'+'set'='DINNER-SET'
(Other definitions for dinner set that I've seen before include "Collection of plates and dishes" , "Plates etc" , "might be taken out for a meal" , "Complete service of plates and dishes for a meal" , "crockery" .)
