Wonderful birthday meal that I was treated to here. Opted for the Thai part of the restaurant and was not disappointed. Highly recommend for spice lovers! Service was extremely attentive - almost too much so at some points, sometimes dishes felt slightly rushed but this did not detract at all from quality of food and service.

Highlights: satay, crispy squid, beef, spicy papaya salad.

Will definitely come back.

Great Asian restaurant, nice receptionist, fast, pleasant and attentive service, food was very delicious, for appetizers the crispy squid, pomelo salad & prawn cakes so tasty just the spring rolls , chicken satay & escargot’s the taste was average and we ask for extra roti and the waiter bring it right away without any additional expense.
The crispy seabass  was great and must try as well the king prawns pad thai, the lamp chunk curry was so tender but I didn’t like the curry gravy too much.
Passion fruit panna cotta & sticky rice with mango was so tasty
Overall, it was a great experience, the service was excellent, and the restaurant is worth trying. I highly recommend it and will visit again.

Koyn Thai is one of the finest Thai restaurant in London, having excellent vegetarian options on their menu. Spectacular location, great food and service. Their Green Thai Curry is filled with authentic, aromatic spices and vegetables and is one of the most delicious Thai Curry we have had in London. Their dessert - Passion Fruit Panna Cotta is truly a blend of authentic roots and modern elegance, light, fruit based and very refreshing. Kudos to the restaurant chefs and the staff is very courteous, attentive and amazing with their service. We had an amazing time at Koyn Thai!
