This place is much bigger on the inside than it looks from the outside. There's plenty of seats, but that's about the only plus.
The food wasn't bad, but I don't think it was anywhere near authentic. I had the soon tofu and although the portions were big, the soup tasted quite watered down. The spice level was way lower than what you'd expect at a Korean place.
Almost all Korean places I've been to serve free hot tea. When I asked for tea here, they brought a mug with a teabag and charged over $1 for it.
Hop across the street to Bap Bo and I think you'll get better food.
