He, Raymond Blanc, has a n incredibly good restaurant in Le Manoir aux Quatre Saisons at Great Milton, near Thame as well as a bistro and another premises, a patisserie, in Oxford. The Manoir is superb and a lovely setting....... Nice prices though - however its one of those don't even quibble about price as it is more than worth the ultimate experience - and even the afternoon tea is out of this world (a little more affordbale)

His cookbook Blanc Vite is excellent for a reasonably proficient cook....some great simple recipes.
