Tangled Cassette is a vintage bar in Yongsan-gu, Seoul, on Yongridan-gil, serving wine, cocktails, and coffee. It offers a Lemon Drop Martini, classic cocktails, and a winter signature cocktail, along with simple snacks. The interior has vintage furniture and quiet music, and the cocktails are generous in size. The snacks are simple, so it suits a second round of drinks rather than a meal.
