El Diablo
This must be one of the world's most unusual restaurants. Here, in the heart of Timanfaya National Park, chicken, steaks, and spicy sausages are cooked over a volcanic crater using the earth's natural heat. Be forewarned: the food is nowhere near as epic as the environs, and on chilly days, you might be served cold meat as all barbecue dishes are cooked outdoors, but it's still a worthwhile bucket-list dining experience. El Diablo is situated inside the park beyond the ticket booth, which means you can't eat here without purchasing entry into the park.
