Nigger, please. He's more of a showman than a chef perhaps, but he's nowhere near talentless. He studied in Paris under Michel Roux and has multiple three star restaurants. You don't get a star just because you have a nice smile, you know.
And as far as I know, he's the only actual Englishman to have three Michelin stars in London (his master Michel Roux has a three star restaurant in London as well (the first three star restaurant even) but he's French).
Diss him all you want, but don't say he's a talentless hack.
