오징어 덮밥/o-jing-eo deop bap! It's pieces of squid and vegetables (carrots, onions, cabbage, green onions, zucchini etc) in spicy sauce with rice on the side. Some places do it better than others. When done right, it's nice and spicy, just a tiny bit sweet, with a sauce of nice consistency. If you have a bad experience, try it at another place.
