Their hot pots(Jeongol / ) are the best!
Generous portions, and well balanced. It's not overly salty or sweet compared to "westernized" Korean food restaurants.
Jeongols are just like what my mom used to make. Side dishes are well made as well.
My new favourite Korean food place now.
Also, they are not overpriced. All Jeongols are $25-30, for 2 people. (Possibly 3). Best price to taste/portion ratio I know of.
