Shake Shack Yongsan I'Park Mall 쉐이크쉑 용산아이파크몰점

Yongsan Station connects indoors to IPark Mall, and this branch sits on the mall's first floor, a short walk from the platforms. The ShroomBurger swaps the beef patty for a fried mushroom stuffed with cheese that runs out when cut, while the ShackBurger is juicy but noticeably salty.
