In Season 3, Episode 9 of The Sopranos, "The Telltale Moozadell", Tony visits a zoo on a date with his mistress Gloria and they see a silverback gorilla. Limiting our purview to the greater NYC area (including North Jersey, the setting of most of the series), which zoo was featured here? The Turtle Back Zoo is referenced offhand in Season 1 but they don't have gorillas. e: did a bit of research and according to a fan wiki, it's meant to be the Bronx Zoo but was actually filmed at the Los Angeles Zoo. Not sure if that lines up with their actual respective gorilla habitats (keep in mind this episode aired in 2001)
