The Duke of Edinburgh, who missed the end of the Diamond Jubilee celebrations, is said to be "improving considerably" but he is likely to stay in hospital for the next few days, said the Palace.
The meal, at Marlborough House in central London, followed four days of public festivities described by the Queen as"a humbling experience".
Representatives of all 54 Commonwealth countries, including Prime Minister David Cameron, Canadian Prime Minister Stephen Harper and New Zealand Prime Minister John Key, were at the lunch.
Also attending were the Sultan of Brunei and Sri Lankan president Mahinda Rajapaksa.
Guests were served brie and avocado terrine, wild sea bass and an apple crumble souffle, all washed down with South African wines.
