I was a little disappointed at this restaurant. It is located in a 'swiss village' but doesn't appear to have any swiss food on the menu.
There are a number of mains available on the dinner menu and there is a buffet breakfast available (I didn't try lunch so can't comment).

When I went there they had a menu item called Curry of the Day. The waiter knew nothing about the dish and couldn't tell me what type of curry it was, only that it had meat in it. Not very helpful!

I'd eat there again if I was staying at the Tamar Valley Resort.
