Not a cheap restaurant - budget at least 50 quid a head, and be prepared to be wowed. We felt is was more than worth what we paid. Starting with delicately tempting canapes served in front of a real fire, the meal just got better and better. The restaurant has an awesome view down the Tamar valley, the service was attentive but not intrusive, and the food was very possibly the best meal I've ever had.
Save up, then go and enjpy it!
