Oh yeah - local reference that most non-natives won’t pick up. Tsukiji Dodaco Tavern 築地銅だこハイボール酒場 in Musashi-koyama, Shinagawa 武蔵小山 (Kana’s workplace) is a direct reference to Tsukiji Gindaco Highball Sakaba 築地銀だこハイボール酒場, which is a popular chain of takoyaki/yakitori izakaya bars that are popular all over Japan (and yes, the original store is still in Tsukiji 4-Chome). Even the logo looks almost the same. Oh, as a further joke, Gindaco 銀だこ is Japanese for “silver octopus” (well, they do served takoyaki or たこ焼き) while docado 銅だこ is “copper octopus”.
There is a covered shopping street in the area where fast food shops like Gindaco could be easily found, but sadly, no here (which is near Fudomae station up the Tokyu Meguro line instead).
Yeah, considering the constant reference to the boughie Southwestern Tokyo neighborhoods of Meguro and Senzoku station 洗足駅 in particular in both the original and the spinoff, I think Norio Sakurai lives in the area…
