The first night I was there the cafeteria wasn't open and I was forced. FORCED! I tell you to eat a Big Mac. I can't say it was that awful. It doesn't taste too bad if you haven't eaten all day and you spend the evening writing.
During the school trip we had a Dosirok (a Korean Bento Box). This one was pretty awful. The only edible things in the box were the the rice and the kimchi. The dried anchovies were awfully fishy, the chicken looked like it was seasoned with avian flu, the hamburger was...???, and the octopus donkas...yeah you heard me OCTOPUS FRIED CUTLET tasted like raw pork. I do not recommend a lunch form Hansol.
