Sampling dishes in street, starter from Indonesia packed in flavour (7)
I believe the answer is:
tasting
'sampling dishes' is the definition.
'street starter from indonesia packed in flavour' is the wordplay.
'street' becomes 'st'.
'starter from' indicates taking the first letters (I've seen 'starters from' mean this).
'packed in' means one lot of letters goes inside another.
'flavour' becomes 'tang' (synonyms).
The initial letter of 'indonesia' is 'i'.
'st'+'i'='sti'
'sti' going inside 'tang' is 'TASTING'.
'in' is the link.
(Other definitions for tasting that I've seen before include "Savouring" , "Sampling (food)" , "event with wine" .)
