Unique and highly recommended! A social enterprise using the kitchen and dining area of a place like a "care home" but more a supported living home. Cafe, pastries and lunch all excellent! Lovely staff and residents. Open to public on Tues, Weds, Thurs, from 9:30 to 14:30. Check website for precise hours. https://www.waste2taste.co.uk/

Most of the gravel has been removed recently, making the lane a little bumpier than usual. Nonetheless great little car-free lane!
