We went for lunch without booking. On the menu all sandwiches can be made gluten free and also a couple of main meals to choose from. The bread on the sandwich was really good. Unfortunately only one sweet treat to choose from, which I didn't try so cannot comment. Overall a good experience.
Rang ahead to confirm there were gluten-free and the assistant was very helpful and explained they could change/cater ther menu to suit. When I got there the waiter explained I was to pick anything on the menu and they would adjust for me. Another waitress came over with a list of items written down that were safe and confirmed my choices were OK. Would highly recommend for breakfast.
