Just returned from a week in London, where I ate at 6 high-end restaurants. I had two fabulous meals, one at Petrus and the other at Hibiscus. Petrus edged out Hibiscus for top place. Two meals were very good: at The Square and Pied a Terre. One meal—at Le Gavroche—was mediocre. However, it was better than the meal I had at Sketch, which was the worst food I have ever eaten at a highly rated gourmet restaurant.
