For gluten free/celiac this place is excellent as far as buffets go. As always when eating out, and especially at buffets, there is a risk of cross contamination, but the staff here are very conscientious and follow good food safety protocols. Definitely ask for a chef allergy tour because they can point out sections that are not always labeled GF but are entirely gluten-free, like their cold sea food bar, and most of their hot carvery stations. Most GF items are labeled, but some GF items are not labeled, which is why the chef tour is important. Gluten free crepes are excellent and they cook them on a separate stove and wear gloves to prevent cross contamination.
Desserts! They had half a dozen gluten-free desserts when I went. The chocolate chip cookies are amazing, but they have them in a rack underneath non-gf items, so if you're sensitive to cross contamination you should ask for a cookie from the warming racks in the back. Even better, they can make you a s'more with a GF cookie as a base instead of a graham cracker, delicious. Gelatos and vegan donuts are also GF, though the donuts used tongs that are used for non-gf donuts as well, so I asked for a staff member to grab me one to avoid the tongs.
Service was great, food was great, staff was very accommodating of gluten allergy, five stars, thanks Chef Jesús for the allergy tour and the s'mores recommendation!
