Very nice shop with many debts (9)
I believe the answer is:
delicious
'very nice' is the definition.
(I've seen this before)
'shop with many debts' is the wordplay.
'shop' becomes 'deli' (deli is a kind of shop).
'with' is a charade indicator (letters next to each other).
'many' becomes 'c' (C is the Roman numeral for 100).
'debts' becomes 'IOUs' (promises to pay debts).
'deli'+'c'+'ious'='DELICIOUS'
(Other definitions for delicious that I've seen before include "Luscious, toothsome" , "Delightful; tasty" , "Yummy" , "very nice" , "Scrumptious" .)
