If you are hungry or thristy while waiting for the bus at the Jeongeup Express Bus Terminal, there are at least 2 stores at the main building selling some food and drinks. Normally during the bus journey around South Korea, there will be at least one rest stop along the way for people to go toilet, buy some snacks and drinks again so this is rather convenient.
There are some stores along the row of shophouses next to the Jeongeup Express Bus Terminal which sell some interesting local food, including the fruit shown in the photograph (unfortunately I did not know its name). This fruit resembles a mini-banana surrounded by a soft shell. Apparently you are not supposed to chew the fruit when eating it. You need to bite very small pieces and then swallow the pieces whole. Interesting indeed but the fruit itself is quite plain with not much taste :)
