Most of the menu (meat trays, salads, some starters and sides etc.) adaptable for GF - you will have to ask the staff, but they're knowledgeable (eg. asking if it's dietary or coeliac related) and happy to talk through the menu. If you're going for the vegan options it may be a bit harder since a lot have seitan in, so I'd get in touch beforehand to see what is possible. When we went one of the local beers was (coincidentally) gluten free (shout out to Yorkshire for having multiple GF breweries!), but even if they change their menu they have other options.
