He famously enjoys a well-done steak lathered in tomato ketchup, followed by one or two scoops of vanilla ice cream - and President Trump clearly thinks what is good enough for him is good enough for the future King of England.
To wash down this very upscale version of steak and potatoes was a bottle of white wine costing $54 a pop, allowing tee-total Trump to raise a glass to royalty and toast Charles, before finishing the evening off with some well deserved ice cream.
Revealing a touch of knowing irony considering the administration's battle with accusations of collusion, the wine hails from Sonoma County's Russian River Valley and goes for $300 a magnum.

Melania Trump selected the menu for the meal at Ambassador Woody Johnson's residence
Guests at the black tie dinner dined on on fresh burrata cheese with heritage tomatoes, basil, and Maldon salt to start, then scoffed grilled fillet of beef with pommes Anna, watercress pure, celeriac and chantenay carrots at Winfield House, the US ambassador's residence in Regent's Park, central London.
Trump swapped his love for fast food burgers for the posher meaty dish as he and wife Melania followed the main with summer berries, homemade vanilla ice cream with Muscovado sugar tuile.
But the teetotaler would not have quaffed the Californian white 'Heart of the Vineyard' and red 'North Block' 2016 wines served throughout the evening at the residence of NFL New York Jets owner Woody Johnson.
He was seen clutching a glass of the white vintage but was actually sipping on a cola drink instead.
