I'm coeliac and until very recently my partner was a chef here - they are very knowledgeable about allergens and are very careful to prevent cc. Always mention that you are coeliac etc. They have GF buns to make burgers etc and they do amazing Sunday roasts with GF veg gravy and may even do GF Yorkshire puddings. It's also a beautiful restaurant by the docks.
New chef now - will need to go again to confirm it's still as good :)
