Been here numerous times for afternoon tea. They bring out a separate stand for you to use with gluten free sandwiches(fresh bread not just genius bread), 2 gluten free scones and a selection of other pastries. And for the jam and clotted cream you get your own jars. I spoke to the waiter and he told me 95% of their a la carte menu is gluten free. Amazing place.
