Shake Shack Special 'The Emilia Burger'

[@yesiamben] At lunchtime on Sunday I popped along to Shake Shack in Covent Garden to try a very special, limited run of 500, first come first served burger. The 'Emilia Burger' (named after the Emilia-Romagna area in Italy) was a collaboration between Shake Shack and Massimo Bottura, the owner and chef patron of Osteria Francescana. For those hearing the name for the first time, Osteria Francescana has 3 Michelin stars and was ranked the world's 3rd best restaurant in 2013. He'd made this burger as a limited special in New York for Columbus Day (and apparently it had gone down pretty well), so I was kind of excited to give it a go.
