Serves meat, vegan options available. Pub/restaurant chain, be warned that it's a carvery and is primarily meatstuff, but it's an option to go with non-veg diners. Vegan dishes might be an allotment pie, a curried veg bake, or another. You could also order a few sides to make a meal, like roast potatoes, stuffing, apple sauce, cranberry sauce, mint sauce, etc. Help yourself to vegetables from the carvery next to the meat. Ask about butter use.
