It's an on-the-edge dining experience. If you're scared of heights then this is your nightmare - a glass-floored, cliffhanging Copper Canyon Cocktail Bar in Mexico.

Set atop the cliff overlooking Mexico's Basaseachic Falls, the second highest waterfall in the country, the restaurant designed by Tall Arquitectos is currently in proposal phase.

The restaurant will consist of two levels with the lower level featuring a bar on one side, tables on the periphery for guests to enjoy the breathtaking scenery and a glass floor in the centre that provides diners a dizzying view of the overhanging cliff.

A rooftop observation deck on the upper level will allow patrons to take in more panoramic view of the landscape. One can relax on chairs, tables and couches or take a swim in the pool on the upper deck.

If the plan becomes a reality, then Copper Canyon Cocktail Bar will be among world's highest restaurants.
