Byron Hamburgers

Byron (legally incorporated as Famously Proper Limited), is a British restaurant chain offering a casual dining service with a focus on hamburgers.

[1][2] In July 2020, during the COVID-19 pandemic in the United Kingdom, the chain closed outlets as part of a deal transferring 21 remaining sites and 551 staff to a new owner, Calveton UK.

[4][5] The burger chain was founded in London in 2007 by Tom Byng, who developed the idea for the company while living in New York City, during which time he would regularly eat at the Silver Top Diner in Providence, Rhode Island.

[12] Just over a month later, on 31 July 2020, the chain announced it was permanently closing more than half its 51 outlets, with the loss of 650 jobs, as part of a deal transferring the remaining 20 sites and 551 staff to a new owner, Calveton UK.

[16][17] A customer suffered an anaphylactic reaction after eating grilled chicken marinaded in buttermilk at the Byron restaurant at The O2 Arena in London on 22 April 2017 and died.
