Earlier this week, the brothers Michael and Bryan Voltaggio, American chefs and former "Top Chef" contestants, traveled to Copenhagen for the third MAD Symposium, an annual food festival that brings together chefs and farmers. Curated by David Chang and his Lucky Peach team, this year's two-day sold-out symposium was dedicated to guts - meaning both innards and courage. Chang introduced the theme literally, however, by bringing out the butcher Dario Cecchini, who proceeded to carve a pig on the stage. Between events, Michael, the chef and owner of Ink in Los Angeles, and Bryan, the executive chef of Volt restaurant in Maryland, caught up with fellow chefs and friends. Here, Michael shares his photos from the event. Slide Show: Food and Friends in Denmark
