The entrance to Alux Restaurant in Playa del Carmen, Mexico. It's a Mayan restaurant with a twist – tucked inside an old, dried-up cenote. As you walk down this stone staircase, you enter the cave which is full of winding pathways through the large restaurant, with separate private dining areas, a bar, and even a nightclub – all underground with the raw elements of the cenote surrounding you. Most importantly, the food was excellent, and so were the cocktails. Great for a romantic dinner.
