More recently there have been signs that diners are starting to lose interest in the group.
One of Salt Bae’s New York restaurants closed in May, with a spokesman saying Nusr-Et had tried a host of markets with some working “while others haven’t”.
It followed the closure of Salt Bae’s Manhattan burger restaurant last year.
The London Nusr-Et Steakhouse has similarly come in for criticism. It is ranked 15,018th out of 15,422 restaurants in London on ratings website Tripadvisor, with clientele criticising the atmosphere, value and food.
The Telegraph’s food critic William Sitwell said the price of a starter of tuna tartare, at £35, was “inexcusable”. It subsequently lowered some of its prices last year.
The criticism of the restaurants has come alongside controversy for Salt Bae.
He found himself at the centre of a row in 2022, when he gained “undue access” to the pitch after the World Cup final, prompting an investigation by Fifa.
He later said: “I can’t do anything about the reason I was there, but I would never, ever step on the World Cup pitch again.
“There were two billion people watching the World Cup … How many people are speaking about me? Five billion. The whole world.”
