They have a small gluten-free menu to choose from. Not highly exciting- fried veg or chicken without soy sauce, but this restaurant is so worth it for the VIEW over London and Kensington palace gardens and the fact that the service is phenomenal. Really friendly and efficient. Great cocktails and nice bar up there on the 10th floor too. And the food for those who aren't gluten-free is great, especially the Peking duck you have to pre-order. Expensive but a wonderful treat.
