Unfortunately, it seems the person below wrote the following four negative reviews. Just a bad experience I guess. This unfairly reflects the true dining experience one can have at Yas. It is not the Ritz and does not try to be. It is a first class Middle Eastern restaurant.
Remember, English is not their first language and you are not there for that rather you are there for a taste of authentic Iranian cuisine. You would be hard pressed to find anything comparable in London and in fact the best test is to try somewhere else first and then see for yourself.
Here, you will experience delicious fresh hot bread from the open oven, tasty, tender grilled meats cooked in front of you over an open pit, some of the tastiest vegetarian appetisers out there and washed down with a choice of soft drinks to fine wine.
Once done you can enjoy traditional Persian tea, fragrant homemade ice creams and sorbets and if you are inclined, you can sit outside and watch the world go by smoking a traditional flavoured 'hookah' until 4am!
And no, I am not the owner or even related. Just someone that enjoys good quality food.
