Smartly dressed members of protest group Animal Rebellion have occupied tables at a Michelin Star restaurant, as part of a day of action.
Nine supporters have disrupted the service at Newcastle’s House of Tides, where dinners start at £130 per person.
Smartly dressed members of the group have sat at tables reserved for customers and holding mock menus outlying the group’s demands.
The sit-in is the first of several expected tonight with protesters set to occupy other restaurants in London and Birmingham.
House of Tides was targeted by the group as it does not cater to vegans, according to the protest group.
Protester Robert Gordon, 26, a former animal care assistant, said: “This action is the first of multiple high-end restaurant sit-ins that will be happening across England this evening. We are targeting these venues in sustained action as they are symbolic of a broken system.
“Households in the North-East have the lowest disposable income when compared to other regions in the UK. Yet House of Tides continues to profit off a wealthy minority by serving meat, dairy, and fish at the expense of our natural world.
“Instead, luxury restaurants like these should be leading by example and transitioning to serving sustainable, plant-based foods.
" A plant-based food system could eliminate the suffering of the one billion farmed animals, and many more fish, killed in the UK each year.
"This would also free-up space for crucial rewilding to draw-down carbon from the atmosphere and restore our countryside, coasts, and precious wildlife”.
Police have arrived at the high-end restaurant and were seen talking the protesters.
The menus held by group members reads: "This menu would spare the lives 1.2bllion land animals and more than three million sea animals in the UK every year.
"This menu would eliminate 70% of food-related emissions and draw down 150 gigatons of carbon from the atmosphere.
"This menu would provide more than enough affordable, nutritious plant-based food to food everyone."
The action comes a month after members shut down Gordon Ramsay's three star Michelin restaurant in Chelsea, west London, when they sat at reserved tables in smart casual clothing.
They held mock menus outlining the environmental costs of items served on the restaurant's menu, including steak and veal.
At the time Lucia Alexander, a 39-year-old auxiliary nurse, said: ""This restaurant is the perfect example of the inequality we face in the UK right now.
"Whilst Gordon Ramsay serves food costing a minimum of £155 per person, more than two million people are relying on food banks in this cost-of-living crisis.
"Instead of restaurants making colossal profits at the expense of animals, workers, and our climate, we need to feed everyone by supporting farmers and fishing communities in a transition to a plant-based food system."
