Read the recent reviews and was hungry last week after returning across Roborough Downs. This is still a humdrum old fashioned road side cafe used predominantly by older people. The food is very ordinary, still quite expensive and the room is a bland environment with a seventies flavour to the decor. If you are a pensioner with time to kill and aren't discriminating and demanding as to what you eat then come out for a drive and then kill a couple of hours in here. Bare in mind though that although it is very close to open moorland, the views through the windows are of a busy main road.
Worth mentioning perhaps that the location at the heading of the Tripadvisor listing is misleading. The building and car park are on the northbound side of the road, ie to your left as you drive towards Yelverton..
