This is considered one of the very best restaurants in the world, and if you are looking for a place for a very special occasion, do not hesitate to book this place for a GF diet. With advance notice, they first call you to confirm whether you are casual or celiac, upon arrival they will bring you special GF tea sandwiches for your afternoon tea, they will have GF accommodations for every sumptuous dinner menu (including excellent bread), they will bring you special items for breakfast, and you will not want to leave. Beyond the accommodation for GF, the place is utterly sublime. Everything is beautiful and delicious, whimsical and delightful. By all means, go.
