Don't go alone and don't go in large groups...
First off, this was the only Michelin-star restaurant in London so far where I felt that service was clearly below the bar and quality of food was slightly below the bar.
With a reservation and a call that I would be 20 minutes late, I still had to wait for my table being set up when I arrived. The waiting time was short though, only 5 minutes.
Overall, the restaurant is very packed and it is very noisy giving it an atmosphere of a canteen with a very beautiful aquarium. On top of that you have fairly loud music which makes conversations between groups of people harder.
Given that I am a huge fan of discovering new food and restaurants, I most often go for the tasting menu. In this venue though I was being explained that I could not get any (!) menu (there were 3) given that I was dining alone!
So I went for 3 signature dishes/dim-sum, chosen by staff: Scallop shui ma, Wagyu beef puff and Prawn and bean curd cheung fun.
The Wagyu was good, 15/20, the Prawn dim-sum was less good (13/20) and there was just too much of the same (for one single person). The scallop dim-sum was in my opinion below the bar (9/20) and it was served burning hot, making the first dim-sum an unexpected burning surprise.
Overall, I would have strongly preferred a selection of different dishes/dim-sum instead of having to eat 10 of the same (prawn). The menu (for which I cannot comment given that I was dining alone) is probably the better and more fulfilling choice!
For desert I ordered (twice, given that I was asked twice the same question) a glass of Sauterne, White tea and the Tropical dome (12/20). Unfortunately the white tea never arrived.
Overall the service felt rushed and stretched. In my opinion, there are too many customers being serviced by not enough staff. This gives the venue the unfortunate atmosphere of Taylorism (a factory). In order to get attention of the staff (to order or to ask for the desert menu) I always had to pro-actively reach out to someone by calling someone 'running' past the table.
On a side note and not influencing my review: During the entire evening my water glass was just filled once which is odd. I would either don't provide the service at all or for the entire large bottle...
The bill was a surprise given that the white tea I ordered twice but never arrived made its resurrection on the billable items. After providing the feedback that I did not receive the white tea, it was removed without providing an apology or without removing the service charge (13%). At this particular instance, I decided to not pay for the service charge given this little incident, my burned tongue and the service that was below the bar for a Michelin-starred venue in London.
At that moment the manager asked for feedback (the very first and only one that evening) and removed not only the service charge but also gave an additional discount of 10 GBP. Thanks for this!
Overall I am disappointed and would not go back alone.
I might give the restaurant a second chance when trying one of the signature menus (with a maximum of 4 persons) but I am almost certain that this restaurant will never make the top list of my favorite restaurants.
Finally, I ate better Dim-Sum at venues that charge a fraction of the price.
