We always went to the Kale for lunch as we loved the view and the Chicken Caesar Salad. Last September we went up and were amazed to see the interior was now totally stripped of all the trappings. There was one "waiter" for the whole place and he did not seem to know what he was doing and was obviously not a waiter. We ordered and waited. We got our meal and then had to ask for cutlery etc., The meal was terrible and some of the chicken was not cooked. We asked for coffee as we always loved the coffee there, unfortunately, the coffee machine was gone and we were offered "nescafe" Had to say the place was a shambles and we were so disappointed. We did not go back this year, but hope you will put a report after you visit so we can see if anything has changed.
I would recommend the Kings Garden, lovely view, not far from the Kale, closer if you are walking and good food and great staff.
