The family of a teenager who died after unwittingly eating food he was allergic to at a Byron Burger restaurant say they do not feel properly compensated.
Owen Carey, who had a dairy allergy, ordered skinny grilled chicken at Byron s O2 Arena branch in London for his 18th birthday in April 2017.
He informed staff about his allergy but was not told buttermilk was included. He collapsed and died shortly later.
Byron said it has since improved all allergen procedures.
The Carey family are now working to change the law. They received a letter from Byron s chief executive apologising for all the pain the family had suffered.
