A multifaceted Asian dining destination in the heart of Mayfair. Discover our fiery Thai dining and our Izakaya style KOYN bar.

Something exciting is coming to the cosmos of KOYN.
In June, our subterranean dining space will transform into KOYN Thai in collaboration with Bangkok born chef, Rose Chalalai Singh. The new restaurant will celebrate the flavours, spices and cooking techniques of Thailand.

KOYN Thai will sit underneath its Japanese counterpart, in the basement of the Grosvenor Street Residence, offering a menu that captures the essence of Bangkok, Chiang Mai, Phuket, and the central provinces.

Rose, known for her Parisian private dining restaurant, Rose Kitchen, and having catered for
some of the world’s greatest fashion and art talent - from Vogue Paris fashion events to The
Gagosian - will make her London debut at KOYN Thai.

Food was very good, service was very poor. Not many people eating and not many staff. The staff were nice but very slow, and drinks took ages to come. Also when I went into the women’s toilets the cupboard door was open with all the cleaning chemicals in.

A great evening in Valentines. Service was very good. Menu explained and felt comfortable. Decor and setting excellent for a romantic dinner. Would gave gift. 5 star however, the main which we had the Seabass wasn’t as good as the starters. Overall lovely place for a dinner with your partner

Great ambiance as soon as you walk in. Had drink in the bar, very well stocked and knowledgable staff. From here we could see into the Japanese kitchen, though we were having Thai so we headed down to the Thai restaurant area downstairs. Again, there’s an open kitchen and a great feel to the room. Food was delicious! The serving staff were lovely, thoroughly enjoyed our evening!

The food was vaguely reminiscent of good Thai food. It tasted like corporate food. Not worth it. The music piped in was a deal breaker. Thumping whatever. Just no. The service was good but the restaurant was empty, as most places are right now, so can't say how it would be when they are busy. Jamavar, which this Indian group also owns, is great, but this is meh.
