 Francisco Rafael's discothèque was a major nightlife attraction in Mazatlán during the mid-1980s.With an estimated US$5 million investment to build it, Frankie Oh had the capacity to host 2,500 people; it had an internal waterfall and a large dance floor surrounded by a fish tank.The nightclub's theme also mirrored a zoo because it had several exotic animals, including two lions, in the entrances and in the surroundings.
