The man was assaulted with a large knife, and received minor wounds to his wrist and arm.
A 32-year-old man was arrested at the scene of the incident in the car park of the Red Dragon Centre.
The assault happened at 7pm, outside the Miller and Carter steakhouse.
A stolen car was reported to have been found crashed and abandoned near the scene.
A spokesperson from South Wales Police told Wales Online: “There was a nasty assault in the car park of the Red Dragon Centre and a person was arrested”, adding: “One male was assaulted and received a cut to his left wrist after being struck with a large knife”.
