I've heard the Ledbury is really good, yet to go though. There was a few I was surprised not to see in the list though including; Alain Ducasse at the Dorchester, and also Le Champignon Sauvage.
Ate at Le Champignon back in August and we were very impressed. Not quite as polished or adventurous as Petrus (another 2* place), but still VERY good.
Is the list worth googling for reference, or is it one of these "personal opinion, take with a pinch of salt" things?
