Blueshack Yeonsan is a coffee shop in Yeonsan-dong, Busan, selling lattes and coffee. Its signature Shaq Latte is an Einspänner coffee that combines lightly sweet cream with strong espresso. Unlike many Blueshack chain branches that are takeout-only, this location has seating and closes at 8:50 p.m. It does not offer a large size, so the drink volume is limited.
