Hate to be the dissenter here, but DH and I went for our 5th anniversary, tried the degustation menu and weren't overly impressed. Some of it had to do with our waiter who barely spoke English and couldn't answer any of our questions about the menu. But in the end it was the food that failed to wow. For the price we paid for the degustation menu with wine, we should have gone to V&A's and had the regular menu there without the wine.
We ate at Jiko earlier that same week and the meal was simply amazing, couldn't find a flaw if I tried.
