Coya is at basement level, sensitively lit (dark) and fittingly hot. In fact, it reminded me of heady nights in Buenos Aires last winter, post-polo, with a tan from a day spent watching men in tight riding trousers, and not the way I’d actually spent my Saturday — watching Keeping up with the Kardashians (Kim is pregnant!) and hiding from my cleaner. Coya is also loud. The South Americans have no respect for po-faced British dining traditions: the sad rattle of the soup spoon and the gentle hubbub of people enquiring about each other’s UPVC extensions. Oh no. Here it’s very buzzy (could everyone stop standing on my feet on the way to the loo, please?), slightly chaotic (expect a cloakroom scrum), and — importantly — from the moment you enter the main dining room, it smells delicious, thanks to hot grills full of tamarind-glazed costillas de chancho (pork ribs) and chuletas de borrego (lamb) with crushed aubergines.
