As a Korean who was born and raised in the heart of Minnesota "midwest-nice", I have to say that I love this place with every inch of my being. The food reminds me of my mother's (who is a fantastic Korean cook). It's the only Korean restaurant I've been to in the Metro area that serves good, soulful, down home Korean food, and believe me, I've been to them ALL. The new ones, the old ones, the fancy ones, the crazy ones. Dong Yang is the tops.
As to the haters who don't like the "service", you can go to Applebees to get some cheesy smiles and flair. Think of this place like your grandma's kitchen: she serves you immense portions of her famously good food, slaps your hand if you try to sneak a pinch from the stove, and wipes food off your face while you try to fight her off. The ladies who churn out the cuisine are just like that. Koreans, and particularly old Korean ladies, are not going to lick your shoes while they cook your food for you. It's a cultural tick that might be hard for some hoity toities to understand, but you might notice that it never bothers the Koreans who eat there, it's what we were raised with. They'll yell at you like you were their kids, but never in a mean-spirited way and always with a serving of amazing Korean cuisine. Go, enjoy the experience. Your stomach will thank you.
