The wife and both felt that this was the best dining experience we've ever had between the food and the service. Ambience is pretty spectacular as well although we did not have a window table.
I've seen comparisons to Guy Savoy which we have eaten at as well. While the presentation at Guy was definitely a wow factor the food and ambience was superior at Twist. I won't get into food details because I'm not articulate enough in the way of foodies to adequately describe what I had other than naming the dishes but it was simply an incredible experience. Don't miss it if you plan on splurging.
