Police were called to the outlet on the corner of Elles Rd and Tay St just after 5.30pm after receiving a report of two groups were fighting outside.
The first officers at the scene discovered ‘‘a lot of blood’’ in a toilet on the premises and closed the restaurant.
Police were interviewing several children and their guardians "at the scene and at the station", a spokeswoman said.
A St John spokeswoman said a boy with moderate injuries was taken by ambulance from the restaurant to Southland Hospital.
The restaurant manager, who did not want to be named, said the restaurant reopened about 7pm.
