We are just back from ten days in the area. we had lunch on two occasions at Delaire Graf Hotel and restaurant. There are two restaurants so we tried both. Members of our group thought that it would be a wonderful place to stay. The location is superb, the winding uphill entrance drive is beautiful and the building and its grounds are so cool.
But it is a bit isolated, between Stellenbosch and F'hoek and for some that is its charm. It is also not cheap!
If you have the time, go for lunch.
