Thousands of people who had booked a meal at Red Hot World Buffet in Northampton, including 700 people hoping to eat at the restaurant on Christmas Day, are being forced to make alternative arrangements.
James Horler, chief executive officer of Red Hot World Buffet, said the company was doing everything it could to accommodate customers at their sites in Milton Keynes or Nottingham.
Mr Horler said a total of 33 people worked at Red Hot Buffet in Northampton, including 18 full-time and 15 part-time.
He said: “The main thing is that no one was hurt in the fire as I believe the speed at which it swept through the roof was frightening.”
Mr Horler said the fire started in the front of the restaurant, not in the kitchen area. He also said the firefighters job was made more difficult by exploding gas bottle stored in the cellar of the restaurant.
Mr Horler said a decision if and when to reopen the restaurant would be taken once he had visited the site and spoke to the insurance company.

A spokesman for Northants Fire & Rescue said all fire engines had now left the scene and fire investigators were hoping to establish a cause either today or tomorrow.
