I think this place is closed...
Went to the address found by Google Maps, across the street from the Parque de la Rehoyada. Walked around several of the streets on the area and didn't find anything. The guy at the Aztec hotel said there used to be a place a few blocks away, but it closed. There is another one called Closet de Laser that's open and in a kind of sketchy area near Bonampark & Avenida Revolucion. Not too many guys, but most were pretty hot!
