He already has two Michelin stars to his name at his eponymous restaurant and now Claude Bosi is getting into the burger business. If you were watching Snackmasters on Channel 4 last night, you might have seen him recreating a Burger King Whopper in his own style - and now he's brought that to his Oyster Bar, downstairs at Bibendum.
The Bosi Burger is an eight-ounce beef patty, topped with Swiss cheese, Guinness-fried onions and crispy Alsatian smoked bacon then flaked sea salt and freshly ground pepper. It's all in a toasted sesame bun with the Bosi Burger Sauce - that's mayonnaise, tomato ketchup and lemon juice, with gherkins and gem lettuce to finish.
So if you want to see how one of the UK's top chefs does with a burger, head on down. The burger's on sale now, for £16.50 with fries.
