And Richard Angell kept good on his promise, heading back to the restaurant the very next day.
"I've got to pay my bill," he told Buzzfeed News, "Also, we haven't given the staff a tip, and they looked out for us when they should have been helping themselves. It was lovely food and I want the rest of my main course."
Many have echoed Angell's sentiments and defiance, in addition to praising the emergency services who kept everyone safe amid the chaos.
London's mayor, Sadiq Khan, also released a video statement on Twitter, vowing that London won't be so easily frightened:
As the U.K. mourns the victims of the London and Manchester attacks, the world is showing support the best it knows how.
But it's important to keep in mind that, as Angell so eloquently said, "small-minded, cowardly, evil people should not change our way of life."
