Set against a dimly-lit cavernous atmosphere, the Cave Bar in Petra is touted to be the oldest bar location in the world. The bar is entombed in a rock carved by Nabateans nearly 2,000 years ago. Today it is part of the Petra Guest House, and is characterized by a grand piazza at the entrance. The insides are hazily lit, with lush armchairs for comfortable seating. Enjoy a cup of Jordanian red wine with small bar food such as potato wedges and fish and chips.
