This episode is directed by actor Fernando Lamas
The hot dog scene was filmed from a now demolished overpass , however a relative same view can be seen from the surrounding buildings at 2112 Avenue of the Stars.
Uber-charismatic and perennial guest-star, Liam Sullivan, he of the arguably most popular episodes (which he filmed back to back) of Dragnet & Star Trek, plays an elegant bad guy here.
Veronica Hamel would play a much more memorable and dramatic role as Hutch's ex-wife in season 3's Hutchinson for Murder One (1978).
Even though Starsky's undercover name is "Ramón", this is not the famous "Donde está Ramón?" title. For some reason, the writers seemed to really like the name "Ramón", since they used it twice. It could be that they had never heard of "Alejandro", "Miguelito", "Paco" or "Fernando", to add some variety to their chosen Spanish names.
