Using an exciting – and questionably safe – food preparation technique, the chefs at the El Diablo Restaurant on the island of Lanzarote [in Spain] have a one of a kind kitchen, a volcanic hole in the ground.
Building a restaurant on top of a massive heat source is not the easiest task. Architects Eduardo Caceres and Jesus Soto had to lay 9 layers of basalt rock in lieu of digging down to build a foundation. A giant grill is laid across the opening, where 6 feet below, the gentle giant is softly bubbling lava at 400 degrees Celsius, apparently the perfect temperature for volcanically grilled meats.
