There were actually two parts to the establishment, one above and one below the surface. Above the surface wasn’t just a waiting area, it was called the Metro Bar, which offered views of the Gulf of Aqaba.
Below the surface was the bar in the previous photo, and a dining room. Atlas Obscura noted, “the underwater area roughly resembles the shape of a star, hence the name of the place.”
We even found a travel video from someone who went there.
