The King-Kong was a real first class bar, at 32 Calle Mina, Cuauhtémoc (address shown in close-up on a medal at the ape's chest) - northwest of and close to City of Mexico Historical Center. As the movie shows, it was a large place, with tables around a large dance space and first floor boxes with tables. It featured shows of live music, singing, exotic dancing, and according to Cuauhtémoc's Delegado (public prosecutor), Parra Montes, it was one of 110 "vice centers" closed down between 1979 and 1981. According to that judicial authority, in those places there were very poor quality shows, prostitution, prostitution of minors, and other dangerous activities. The civil servants wanting to enforce the law were subject to pressures, menaces and attempts of bribery, and he mentioned that the management of the King-Kong in particular, in 3 years, had won 13 judicial decisions (juicios de amparo) against administrative orders of closure,
which brought up suspicions as usually each case of forced closure took two years in court before a decision. The film was shot in 1978 (possibly the third quarter), and it opened in 5 theaters of Mexico City
in December 3, for 2 weeks - seven months after the re-opening of the King-Kong that caused uneasiness at the Delegacia de Cuauhtémoc. It seems that re-opening was not going to last.
