Activists have targeted the Knightsbridge steak restaurant owned by Salt Bae.
The Animal Rebellion group, an offshoot of Extinction Rebellion, said eight people entered the Nusr-Et steakhouse in the upmarket central London district at about 6pm and sat at tables which were already reserved.
Salt Bae, whose real name is Nusret Gokce and who shared a picture of himself at the World Cup on Friday, became a viral internet hit for his technique of sprinkling salt on to his dishes.
The protest group said in a press release it is calling for “a plant-based food system and mass rewilding”.
Student Ben Thomas, 20, said: “Restaurants like these are symbolic of a broken system.
“Whilst two million people are relying on food banks in the UK right now, influencer chefs are selling gold-plated steaks for more than £1,000.
“Steaks, and other red meats, that we know carry the highest environmental impacts.”
