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.

    The cocktails were fantastic and reasonably priced for London. We tried all 5 of the happy hour specials. We ate the Thai festive tasting menu and each course was sublime. Full of freshness and flavour. The best Thai food we've eaten and the best tasting menu too! I especially loved the crab curry.

    I cannot express enough how much we have fallen in love this week with Koyn Thai! It is now on our MUST list twice a year…… very fine food, kind and attentive wait staff, gorgeously lit and decorated room, ……… everything was absolutely yummy and fresh……very nice wines, even liked the crowd that seemed to enjoy their privacy and food as much as we did. Thank you Kohn!!!!

    Food was amazing and service was good. Every dish that came out was flavourful and tasty. The portions were good too and not too big. The atmosphere was cool and cocktails were great- especially Sea of clouds! Definitely value for money and would recommend to anyone who appreciates good Thai food.

    The food was nice… I was surprised to see a cover charge for the table… we were totally happy to pay service charge.. but cover charge additional was a bit to much.
