Tasty food but quite limited

Stopped here for lunch and had the cauliflower soup, it was really tasty and filling! The atmosphere was cute and cosy, however there wasnt a great deal of options. Was the usual like salad / vegan burger.

Sunday lunch

Several clearly labelled vegan options and many of the dishes can be ordered vegan. The website lets you filter on vegan and vegetarian menu items. We popped in on a Sunday and had a delicious nut roast followed a an apple and rhubarb crumble with vegan ice cream and a lemon posset.

Pros: Delicious traditional food, Friendly staff., Relaxing cosy surroundings
