Theresa serves Jimmy Lee a glass of beer. Alternating shots show the glass with a thick head or no froth at all.
The cops say "Vino de Casa"... that is Spanish! But they are in an Italian restaurant, therefore they ought to have asked for "Vino DELLA Casa". (Pronounciation in Spanish is "day" vs. Italian's "day-la".) They also pronounced "Casa" in Spanish ("cassa") vs. Italian ("cazza").
Though Starsky has been to this restaurant before & Hutch is there for the first time, it is Hutch who directs Starsky to the men's room & informs him that the jukebox is free.
Starsky, with Hutch, is a frequent patron of Italian restaurants & fondly remembers his grandmother living over one during his childhood, but somehow never came across vino della casa on a menu.
