Tate Britain’s Rex Whistler restaurant will never reopen the gallery announced yesterday. The restaurant – once known for its excellent and well priced wine list – won’t reopen due to the apparent offensiveness of the mural on its walls. Diners used to be embraced by the mural, The Expedition in Pursuit of Rare Meats, a painting by Rex Whistler, an artist best known for his decorative murals in grand country houses.
