His aims - to make food in Tokyo (7)
I believe the answer is:
sashimi
'food in tokyo' is the definition.
'sashimi' can be an answer for 'food' (sashimi is a kind of food). I am unsure of the 'in tokyo' bit.
'his aims to make' is the wordplay.
'to make' indicates an anagram.
'his'+'aims'='hisaims'
'hisaims' is an anagram of 'SASHIMI'.
Can you help me to learn more?
(Other definitions for sashimi that I've seen before include "foreign dish" , "dish from Japan" , "possible accompaniment to 26 [SAKI]" , "food in Japan" , "Japanese dish of thinly sliced raw fish" .)
