, the mini Wagyu beef sliders might sound dainty, but in their steamed buns and topped with cucumber and umami mayo, the result is anything but. They're smoky, sticky and full of flavour. At Lidgate's, the poshest butchers in London, you can take home burger patties made from the UK's only supplier of Wagyu beef. Just don't overcook them. Bobo Social (whose main- course menu is burgers, burgers or burgers) offers the debauchery - a Wagyu patty with an indulgently rich topping of Ogleshield cheese, confit shiitake mushrooms, crispy charcoal-roasted onions, bacon mayonnaise and a generous shaving of black truffle. So get totally burgered.
