Whenever we go somewhere and use the expressway, I always expect to stop by at the Resting Area (Hyugeso). It's not only to take a rest or go to the bathroom but also you can buy different kinds of food. There are lots of korean snacks like hotteok (korean pancake), squids, drinks, and almost everything that you are craving for. I've been to lots of Resting Area but it's my first time to see this vending machine for books.
Sorry for the picture. It was late at night when I took the picture. My hubby likes driving at night because there's no traffic. Besides, he's a night owl so he's more awake at night than driving in the morning.
