In 2018, the pub was put up for sale for ã700,000, at which time it had a bar, restaurant, snug, four hotel bedrooms, and a beer garden. In 2021, The Yorkshireman recommended it as one of the ten best beer gardens in the North York Moors, and described the pub as "no frills" but as having a "homely, cottage-like air".
