We went into the main restaurant, for a pot of tea, and perhaps a piece of cake. Much to our surprise they had four gluten free cake offerings, including the ubiquitous brownie, which my husband wouldn't eat from choice, gluten free or not.
There were two cakes which appealed to him, banana and coconut, and orange and polenta cake. So we ended up buying one of each, and cutting them in half to share. I don't need gluten free, but enjoyed both cakes.
They have sandwiches on offer as well, with a notice saying that they can make any of those fillings on gluten free bread.
Think there were also two salads on offer, with one of them being labelled gluten free.
