South African restaurant customers are complaining that the use of the word tsunami by local eateries leaves a bitter taste in the mouth.
More than 150,000 people were killed by the Tsunami and millions left homeless
The Mugg and Bean chain has been selling its spicy tsunami chicken burger for over a year but will rename it in April, its managers say.
Johannesburg's Tsunami Seafood Emporium opened just three weeks before the giant waves devastated parts of Asia.
The Japanese sushi bar manager said he could not have predicted the disaster.
"A lot of research went into the name," said Claudio Goncalves.
He said that some people thought the restaurant was trying to cash in on the disaster.
One woman has asked what he would think if someone had opened a 9/11 grill house, he said.
Mr Goncalves, and his counterparts at Mugg and Bean, said they would donate some of the profits to victims of the tsunami.
Mugg and Bean's marketing manager Mike Said explained the choice of the name for the chicken burger, topped with bacon, cucumber pineapples and Thai sauce served in a bagel:
"We named it 'tsunami' because the burger is big and powerful."
Ten South Africans have been confirmed dead in the disaster and another 184 are officially missing.
On Monday, South African police warned that conmen were circulating letters and e-mails falsely claiming to be collecting contributions for victims of the disaster.
Meanwhile, a Cape Town family who survived the tsunami while on holiday in Thailand were car-jacked at gunpoint on their return to South Africa.
"I am absolutely traumatised," said Nicky Miller, 31.
