Argentina-raised John Rattagan was the family grill master from an early age, in a country where the asado (barbecue) enjoys near sacred status. Luckily for London, he left his homeland as a young man and set up Buen Ayre in the heart of trendy Hackney. The headline act is the steaks, served in a range of cuts with a simple garnish. Expect warm service, fine Argentine wines and the best steak you’ll taste in the capital.
