Rockhouse is transcendent at night, expansive deck overlooking a cove lit up turquoise (you can explore a few pathways near the water too), lovely flower-filled grounds, great service, Karl Ricketts's paintings adorning bathrooms. In my experience, the most beautiful restaurant in the world. Pretty good food too.
My only issue with Ivans is the one time there for dinner, service was entirely absent once meal delivered. Disappointing. Would give Ivans another chance... if only Rockhouse wasn't just a stroll down the road.
