The Copper Chimney at the Chatsworth Centre, near Durban, was stormed and robbed by four men as the restaurant was closing up on Sunday night, East Coast Radio (ECR) reported.
The men reportedly demanded cash and cellphones from employees.
Mohammed Malik, the duty manager at the time of the attack, reportedly said employees were instructed to lie face-down on the floor for several minutes while the robbers made their getaway.
Malik said he was having trouble sleeping at night following the attack.
"There were four of them [carrying guns]. They started to push us back inside and told us - to give them money. They hit us, demanding more money. We told we don't have money. It was the [worst] experience in my life," Malik told ECR.
Additional security was reportedly being implemented and police were investigating.
A scuffle, screams, and police officers retreating with firearms in hand.
