Top celebrity restaurant Nobu is facing disruption this evening as environmental campaigners have descended on the Mayfair establishment.
The restaurant, owned by Robert de Niro, is currently embroiled in controversy after refusing to stop serving bluefin tuna - an endangered species.
A host of celebrities, including Sienna Miller, Stephen Fry, Elle Macpherson, Alicia Silverstone, Ted Danson and Woody Harrelson, have written to the restaurant saying that they can no longer "dine with a clear conscience" as long as bluefin tuna is on the menu.
