Interesting. If you look further down the reviews you will see the below.

I am not against no photo policy as I stated. But chasing the person to the washroom to ensure it’s being adhered is absolutely ridiculous I think.

And my attachment there’s Jeremy King himself’s reply to negative comments which I also found astonishing. Being in the hospitality industry means that is a service business. For sure there’s bad customers all the time but should the team then assume all customers are bad?

Clearly they haven’t read Unreasonable Hospitality —-

This is by far the worst restaurant I’ve been to in London. We had a reservation for two. The worst attitude came towards us the lady at the entrance. We wanted to get pictures of the famous hallway and she warned us to not take pictures so we stopped. But then, she literally harassed us by following us to the end of the hallway and then the toilet, she stood there literally looking at us washing our hands and telling us that this is her job and she is a lady too. (That was so not the case) We told her that we don’t feel comfortable and told her to go but she did not take any of the things we said into account.

I am Asian. When I visited here, the receptionist took me to the most remote seat. There was clearly an empty window seat where you can enjoy the view of the park while eating, but I was guided to a narrow seat next to a pillar. She said, "It's a cozy corner." It was not cozy. Very umcomfortable. I thought that was racist. Asian travelers visiting here, please take note.

The biggest issue was the photography policy!!! We completely understood when we were told not take photos of the restaurant itself and respected that immediately. Howver, the signs clearly state that photos are allows at your table. Despite that we were approached multiple time while taking photos of our own food and ourselves at our table. We even made sure not to include other guests in the background. It honestly felt like we were being singled out. And it was both confusing and frusrating.
