After refurbishment, Chinese restaurant at first improves (8)

I believe the answer is:

enriches

'improves' is the definition.

'after refurbishment chinese restaurant at first' is the wordplay.
'after refurbishment' indicates anagramming the letters.
'at first' suggests taking the first letters.
The first letter of 'restaurant' is 'r'.
'chinese'+'r'='chineser'
'chineser' with letters rearranged gives 'ENRICHES'.

(Another definition for enriches that I've seen is " Makes wealthy or improves quality".)

I've seen this clue in The Guardian.
