I gave them an extra star only because of all the side dishes they give and I love them all. No nonsense service: if they are busy then you gotta wait, figure out what you want before you call them over or they'll leave, when they are ready they will come over to you, and they will bring you everything you need eventually. Super fast service and food, in and out restaurant. They won't smile at you, and no five star service if you can live with that, but at the same time there's no fake smile, if they are pissed you will know.
They food is pretty decent, I usually have the pork bone soup, the mackerel with tofu soup or the bulgogi in soup. Everything is usually tasty and consistent. We come often for good economical fast Korean food. It gets a bit chaotic when it's too busy. Will definitely come back but maybe not during the busy times.
