Huashan Teahouse, Weinan, China: 2,160 metres
Admittedly this isn’t quite a restaurant, but it’s such an epic location we had to include it. Located on the remote southern peak of Mount Hua, it can only be accessed via a path known as the Heavenly Stairs.
Described as one of the world’s most dangerous hiking routes, in some places it consists of little more than narrow strips of wood and guide chains attached to the sheer mountainside. It’s not a trip for the faint-hearted, but the view is unbelievable and the refreshments at the top will taste extra sweet.
